Westfield XI - Frequently Asked Questions

Q. How Complex Is The XI Build? What Tools Will I Need? How Long Will The XI Take To Build? Are There Any Steps In The XI Build That Are Particularly Difficult?

A. This will certainly depend on your level of skill, but as a general rule, the Westfield XI has been designed as a component kit that can be assembled simply and quickly, with a minimum of complications and a maximum amount of fun.

Westfield estimates that construction of your XI component kit by someone with previous assembly experience will require 120-140 hours of work. A standard set of shop tools will be required, and a specific list can be found within the build manual.

Setting aside the donor engine, transmission and differential repairs or rebuilds, which may or may not be necessary, there are three specific tasks that must be attended to. Most importantly, Westfield has re-designed and upgraded the rear suspension. While the original Midget/Sprite rear suspension utilized a leaf spring with lever shock absorbers, the Westfield XI now incorporates five links, with four trailing arms and a panhard rod. This upgrade to the suspension will require two small brackets (supplied with the kit) to be welded to the Midget/Sprite differential casing. Templates and instructions for this modification are included in the build manual and should take no longer than 30 minutes to complete.

The second modification to the donor vehicle will be the shortening of the driveshaft. It is strongly recommended that this modification should be carried out by a third-party who can subsequently re-balance the driveshaft and allow an easy fitting into your Westfield.

The third, and possibly easiest modification, involves the cutting of the steering column shaft. The donor vehicle"s lower steering column needs to be shortened in order to accept the new upper section supplied in the component kit.

Q. What Parts Are Needed From A Donor Vehicle Or Other Source?

A. Westfield has designed the XI to take certain parts from a chrome bumper MG Midget or Austin-Healey Sprite. You will need to acquire the following items separately:

  • Engine: 1275cc BMC Series "A"
  • 4-speed gearbox (if not opting for a 5-speed conversion)
  • Front uprights (kingpins), including brake calipers, discs and steering arms
  • Steering rack and mounts
  • Dashboard instruments
  • Wiring harness
  • Radiator
  • Battery
  • Pedal Box and master cylinder
  • Handbrake cable, linkage and lever
  • Fuel sender unit
  • Rear axle and drum brakes
  • Wheels and tires
  • Driveshaft
  • Engine and gearbox rubber mountings

    Q. What Type of MG Midget Is Used As the Donor Vehicle?

    A. The Midget/Sprite needed is generally referred to as the 'chrome bumper' Midget/Sprite which has the 1275cc engine. Since some cars may have been modified over the years, it is important you check the engine size. That being said, as per the Midget & Sprite Club website: "Midget MKIII - October 1966 to September 1974. The Midget MKIII was introduced in October 1966 with the 1275 cc engine, along with a revised cockpit featuring a new rear panel incorporated a permanently attached folding hood. In 1967 the vertical radiator was changed to a cross-flow design, which meant the addition of an expansion tank and the necessary relocation of the windscreen washer bottle. In December 1968 the seats were redesigned again, with horizontal fluting and a reclining facility. In September 1969 various cosmetic changes followed, such as the substitution of the chrome slatted grill for a black recessed grill with chrome insert and surround. For a short while, the windscreen frame was also finished in black but soon reverted back to the previous bright finish. It was on this model that the first design of rostyle wheels were fitted in place of the plain steel wheels. The new rostyles had rectangular cut out slots unlike the spoke design of the later wheels, which were introduced in October 1971 when the rear wings were restyled with round wheel arches. Wire wheels remained on optional extra on all models."

    Specific engine and chassis number details can also be found on the Midget & Sprite Club website.

    Q. What Are The Westfield XI Component Kit Options?

    A. While Westfield prides itself on offering a great many options for its customer's cars, the XI is a special situation. The XI kit has been designed to closely match a racing vehicle that would have appeared at numerous tracks around England, Europe and the United States during the late 1950s. As such, you will not find an option for a radio, cigarette lighter or air conditioning. Most customers are ok with these decisions.
    Current options for the Westfield XI are as follows:
    1. Left-hand drive or Right-hand drive chassis
    2. Le Mans-style aerodynamic head fairing "hump" rear body panel
    3. Optional Wrap-around aeroscreen & glass fiber tonneau cover for single-seat cockpit (RHD only)
    4. Full Tonneau cover including fittings
    5. Adjustable bucket style seats or fixed back "bench" seats
    6. Ford "Type 9" 5-speed gearbox adapter kit (if not fitting a Midget/Sprite 4-speed gear box)
    7. Front Anti-roll bar
    8. Chassis support stands
    Note: Authentic red leather steering wheel and chrome mirrors supplied as standard instead of the SVA kit supplied to UK customers.

    Q. What Other Parts Or Materials Will I Need To Finish My Westfield XI Kit?

    A. As with any other vehicle build, there are a few consumables that will be used during construction - silicone sealant, oil, grease, brake fluid, etc.

    Q. Do I Need A Donor Vehicle For The Engine, Transmission And Other Parts?

    A. No. Manik Technologies can help you locate used, rebuilt or race-prepared engines, transmissions, wheels and other parts needed to complete the XI. However, many people find it simpler and less expensive to purchase a complete MG Midget or Austin-Healy Sprite to use as a source for the parts. If you choose that route, you also gain title to the donor vehicle, and that may make State registration an easier task.

    Q. How Long Will It Take To Receive My Westfield XI Component Kit?

    A. Once you have reviewed the materials and have placed your order for a Westfield XI kit, it typically takes around six weeks for your components to be manufactured and crated ready for shipment. At this point your kit is picked up by our shipping company at the Westfield factory in the UK, and brought through customs in the United States. Trans-Atlantic shipping can take four to five weeks, followed by four to five days from the port of entry to your door. From start to finish, your Westfield kit order should take ten to twelve weeks.

    Q. Will I Fit Into The XI?

    A. While the cockpit is understandably tight, someone that is just over 6 feet tall can fit comfortably. However, both the driver and passenger seats are 340mm wide at the hip and may pose a tight squeeze for those of us with a large rear-end. If the need arises for additional width in the passenger compartment, the individual seats supplied with the kit can be substituted for a solid foam back and individual seat squabs for both the driver and passenger seats. The backing and seat squabs are fully trimmed out and have a professional and "factory" appearance. Without the seats, the width increases to 420mm. This is also a good option for XI owners who will be racing their cars and seek a maximum reduction in vehicle weight.

    Q. Does The Parking Brake Lever Interfere With The Driver In A LHD Car?

    A. Since the Westfield XI uses many parts from a Midget or Sprite, mounting and location of the parking brake is retained. In the case of LHD Midgets and Sprites, the parking brake is mounted on the left-hand side of the transmission tunnel. If you devise a way to mount the parking brake handle on the right-hand side of the transmission tunnel, the carpets can be made to suit.

    Q. Can I Choose The Color Of The XI Interior Trim And Carpeting?

    A. The different pieces of the Westfield XI kit have been assembled to create a period correct vehicle. Following this line, the interior has been crafted from a brilliant red that perfectly compliments the traditional British Racing Green of the bodywork. Differing interior color choices from Westfield's own carpeting and trim shop can be chosen to your specifications. However, the leather steering wheel supplied with the XI kit is only available in red.

    Q. Is The Bodywork Aluminum or Fiberglass?

    A. Although the Westfield XI was produced in small numbers during the early 1980s, this re-introduction of the XI has shown many updates to both the chassis, and the bodywork. Utilizing advancements in technology, the moulds for the fiberglass body panels have been reproduced to a much higher standard than the originals. The XI bodywork is produced in-house at Westfield's own body fabrication facility to ensure a very high level of quality. Each body piece is pre-finished in a dark "British Racing Green" gel-coat as standard that can be polished, or subsequently painted during your build. Optional Westfield colors may be chosen for the bodywork, and we have supplied customers with yellow, blue, red and black XIs.

    Q. Do I Have To Paint The Bodywork?

    A. Strictly speaking, no. The XI fiberglass body panels come pre-finished from the factory with a dark British Racing Green gel-coat. This gel-coat can be polished and provides an excellent finish option, ideal for a race-prepped XI. However, those XI owners wanting additional color schemes or levels of finish may want to have the body panels professionally prepped and painted.

    Q. Is A Complete Aluminum Body Available?

    A. Not at this time. Westfield has been unable to locate quality aluminum craftsmen who can recreate the XI body in aluminum for an amount that is reasonably affordable. Sadly, Williams & Pritchard are no longer in business to produce coachwork.

    Q. Will The Westfield XI Body Panels Fit A Lotus Eleven?

    A. Yes, a complete Westfield XI body panel kit will sit perfectly on a Lotus Eleven chassis. However, over the past 50 years, many Lotus Eleven chassis and existing aluminum body panels have been modified. Any use of the Westfield body pieces will most likely need some adjustments in final fitting. If you purchase a Westfield front nose, back end, scuttle and doors they should all fit on a Lotus Eleven nicely. The Westfield body panels match that of a Series 2 Lotus Eleven.

    Q. Will The Westfield XI Body Panels Fit The 'Older' XIs from the 1980s?

    A. Yes, a complete Westfield XI body panel kit will sit perfectly on the 'Mark I' Westfield XI chassis. However, as the new body moulds have been slightly revised and upgraded, customers would be advised to replace all the body parts.

    Q. How Are The Body Panels Secured?

    A. Westfield has chosen DZUS quick access fasteners, which provide a safe alternative to the traditional straps.

    Q. Can The Le Mans Head Fairing Be Removed From The Body?

    A. The optional aerodynamic head fairing is a part of the integrated rear body section and cannot be removed independently.

    Q. What Type Of Wheels And Tires Will Fit The XI?

    A. Generally speaking, since the four-bolt hubs are sourced from an MG Midget or Austin-Healey Sprite, the corresponding 13" wheels will fit. Several choices are wire wheels, minilite-style, or the traditional "wobbly" wheels. Manik can supply all these options separately at the customer"s discretion. If you decide to use the wire wheels that come with your donor vehicle, it is advisable to have them professionally trued and examined before using them. However, many people find the cost of repair on used wheels equals or exceeds that of new wire wheels.

    Hub dimensions for the original Midget/Sprite hubs are as follows:

    • Steel - 4 bolt on 4 (101.6 mm)
    14" or 15" wheels may be fitted to the XI, but special care will need to be given to the bodywork clearances.
    Typically, the factory has been fitting the XI with 165x80x13 tires, but your choice may vary.

    Q. Are There Any Issues Between Wire Wheels And Steel (or Magnesium) Wheels?

    A. One factor that should be taken into account is the rear axle you will be using. There are actually two different types of rear axle casings used on the Midget/Sprite - one for wire wheels and one for steel wheels. Without some modification or adapters, each differential can only support one type of wheel. The wire wheel axle casing is shorter than the steel wheel axle casing by roughly an inch. However the differential gears, rear drum brakes, brake cylinders and shoes and shoe retaining springs & clips are the only inter-changeable parts. The internal half shafts, and rear hubs are not interchangeable between the wire and steel wheel axle casings.

    The front uprights (king pins) are a standard fitment for both wire and steel wheel fitments. The hubs incorporate the discs and either the 4-stud plate or wire wheel spline - both are interchangeable.

    Q. Is There Room For A Spare Tire?

    A. Underneath the rear bodywork section, there is room for a spare tire. However, the decision of where and how to mount the wheel/tire assembly will be left up to you. Most XI owners choose not to include a spare for weight reasons.

    Q. What Are The Specifications Of The Lotus Eleven?

    A. Almost all Lotus Elevens were produced as purpose built racecars. As such, deciding what an original specification is or was may vary significantly from car to car. However, the following list would be period correct for an Eleven that you would find racing around Silverstone, Sebring or Le Mans.

    Standard Engine:
    Coventry-Climax FWA (1098cc) SOHC Inline 4 cylinder
    Standard bore x stroke - 2.85" x 2.625"
    Carburetion - Dual SU
    Transmissions: BMC A30, 4-speed
    Chassis: A mild steel tubular space frame with an aluminum alloy body
    Front Suspension: Double wishbone, coil spring/damper
    Rear Suspension: Strut-type with coil spring/damper
    Steering: rack and pinion
    Wheelbase: 85 inches
    Overall Length: 134 inches
    Track Dimension, front: 47 inches
    Track Dimension, rear: 48 inches
    Wheels: 4 1/2" x 15"
    Front Brakes: 9.5" discs
    Rear Brakes: 9.0" disc or drum
    Weight: Measured without fuel & driver, all tolerances included: 910 lbs.

    Q. What Are The Dimensions Of The Westfield XI?

    Overall length: 144 inches
    Overall width: 64 inches
    Height to top of screen: 34 inches (approx)
    Height to top of lemans headfairing: 39 inches (approx)
    Wheelbase: 90 inches
    Weight: Measured with half a tank fuel: 1,170 lbs.

    Q. What Engine, Transmission And Differential Does The Westfield XI Use?

    A. Westfield has designed the XI around the BMC "A" Series 1275cc engine and 4-speed transmission. These are commonly found in both the MG Midget and Austin-Healey Sprite. Westfield has also designed the XI to work with the Midget/Sprite differential in either the 3.9:1 or 4.2:1 ratios. The XI can also be fitted with a more modern Ford Sierra "Type 9" 5-speed gearbox, although the speedometer will need to be recalibrated by a professional.

    For the re-introduction of the XI, Westfield has redesigned the chassis to accept either the standard Midget 4-speed gearbox, or the Ford Type 9 5-speed gearbox. It is now no longer necessary to specify a chassis for a single gearbox - both will fit perfectly.

    Q. Are There Any Ideal Gearing Ratios for The Westfield XI?

    A. Your situation may depend on whether or not you are building a track-only car, or a street car, and what engine, transmission and differential you will be using. The standard Midget/Sprite setup from your donor vehicle will most likely be the following:

    1st - 3.2 (non-syncro)
    2nd - 1.916
    3rd - 1.357
    4th - 1.0

    Differential: 4.22:1 or 3.90:1 (will depend on the date of manufacture - please refer to the Midget/Sprite workshop manual)

    If you decide to incorporate different gearing, a helpful gearbox and differential calculator authored by Ian Ashdown can be found here.

    Q. Will I Be Able To Get My Westfield XI Serviced In The Future?

    A. The Westfield XI has been designed around a very stable drivetrain that has been in production for almost 50 years. The BMC engines, gearboxes, and differentials are relatively straight-forward and have a large assortment of after-market parts that have been made available. In addition, any competent mechanic can provide appropriate regular maintenance to all other parts.

    Q. Can A Coventry-Climax Engine (Or Other Engine) Be Fitted To The Westfield XI?

    A. Yes, however there were many different varieties of the Climax engine. Westfield has specifically designed the XI to accept the BMC "A" Series engine, and while there are no specific mounting points for a Climax engine (and corresponding transmission), we are aware of several people configuring the Westfield XI with a Climax. Please contact us for further details.

    If you do choose to fit the XI with an alternate powerplant than the "A" Series, please be aware that the BMC "A" Series engine is 23 inches tall from the bottom of the oil pan to the top of the oil filler cap, and the XI's bodywork is designed to just clear the engine.

    Q. If I choose to use a Ford Sierra "Type 9" 5-speed Transmission, can Manik provide an adapter kit or modified bell housing?

    A. Yes. We are making available a Ford Type 9 conversion kit specifically designed for the Westfield XI, and offer it as part of the total kit package.

    It is important to note that the Ford Sierra "Type 9" 5-speed gearbox that was sold in the U.S. for the Merkur XR4Ti and Scorpios has a different (longer) input shaft than the U.K. spec version. You need to confirm with the specific supplier of the modification kit that a U.S. spec "Type 9" gearbox will work. If needed, Manik can help you source a U.K. spec Sierra Type-9 gearbox.

    It should be noted that a 5-speed gearbox will greatly improve the Westfield XI with better cruise RPM, and better performance through a quicker shifting, closer ratio, synchro gear box. If you were to combine this with a more potent engine, you will have quite a nice performing vehicle.

    Q. Is The XI Road Legal In The United States or Canada?

    A. Generally yes. However, due to the many different state and country regulations, a single specific answer cannot be given. However, there are a number of Lotus Elevens, Westfield XIs, and other specialty vehicles that have been successfully registered for on-road use by their owners. Manik Technologies will assist in every way to get its customers cars on the road.

    Each Westfield XI component kit is supplied with a Manufacturer's Statement of Origin [MSO] which defines the vehicle. Since each state and country has different registration procedures, it is the owner's responsibility to ensure that their completed vehicle is registered in accordance with applicable law.

    Q. Can I Fit The XI With A Windshield?

    A. If you are wanting to recreate the look of the Eleven 'Sports' model, you can source the 'flat' windshield off an early Austin-Healey Sprite or Midget. These flat windshields are found on the Austin-Healey Sprite Mk III (up to March 1964) and the MG Midget Mk II (up to March 1964). These windshields should fit directly to the XI's scuttle. Windshield wipers from either period Sprite or Midget should also be used in conjunction with the windshield.

    Q. What About Insurance For The Kit?

    A. There are a number of insurance agents who will be able to provide you with "specialty" car insurance. Property and liability insurance for customers of Westfield kits is considered non-traditional, or non-standard insurance. In order to assist a customer with his or her purchase, Manik can provide unsolicited examples of insurance companies that specialize in specialty or kit car insurance. Some of these companies include:

    • American Hobbyist Insurance
    • Classic Automobile Insurance
    • Condon & Skelly
    • Grundy Worldwide
    • Hagerty Insurance
    • Leland West
    • Motorsports Insurance Services
    • Parish Heacock
    • Sneed Insurance
    • JC Taylor
    • Rally Insurance
    • Tri-State Collector Car Insurance Program

      Most of the specialty or kit car insurance policies stipulate that as a collector's car, a completed Westfield kit can only be driven 2,500 miles in a single year, although some policies are more generous than others. This is where the kit car insurance differs from the general automobile insurance. Insurance companies can also offer the customer a 'goods in transit' insurance policy which covers the time from your kit's arrival, through the building process, and finally on the road.

      Q. Is There A Warranty?

      A. While Westfield and Manik cannot warranty how you build your kit, all Westfield kit car components purchased from Westfield Sportscars and fitted to a Westfield come with a 12-month warranty from date of delivery.

      Q. What Issues Will I Face With Shipping Of The Kit?

      A. Manik Technologies has made it very easy to acquire an XI. All shipping, freight, brokerage, taxes and duties are calculated, and will be added to the final price of the kit. There will be no hidden fees or surprises when you receive your kit. Made at the Westfield factory near Coventry England, your kit will be shipped to a freight terminal closest to your home or build site. Delivery directly to your home or garage can be arranged on a case-by-case basis at an additional cost. Your kit will arrive in a single, but sizeable, crate. You will need to make arrangements to transport the crate to its final destination in an enclosed truck, or on a trailer. Due to the internal mounting of the bodywork, the crate cannot be placed on its side.
      The crate dimensions are approximately:

      • Metric - 3800mm x 1730mm x 1030mm and weighs 600 kilos.
      • Standard - 150" x 69" x 41" and weighs 1,322 lbs.

        Q. Can I Purchase A Fully Built 'Turnkey' Car From Manik?

        A. Not directly. In order for your Westfield XI to qualify as an assembled car for registration purposes, the following three things must happen:

        1. Purchase the Westfield XI component kit from Manik with the options you desire.

        2. In a separate transaction, you will need to purchase an engine and transmission of your choice from any source you like. Manik will be able to suggest a number of companies and places that have the appropriate running gear if you find difficulties. Alternatively, you can purchase a complete donor vehicle for the engine, transmission and other items you will need to complete your build.

        3. The final step is to either assemble these components into a car through your own efforts, or to contract with a shop of your choosing to do that assembly for you. There are many shops around the country that will be happy to do that for you. You may therefore have quite a bit to do with the assembly process, or very little depending upon your desires.

        If, however, you intend to purchase a Westfield XI strictly for racing and have no intention of registering it for road use, Manik can have your car completely built to your specifications. Please enquire for further details.

        Q. Where Can I See Or Drive The Westfield XI?

        A. Since the Westfield XI is very much a low-volume, specialty sportsracer, there is a greater demand than what the factory can currently produce. The good news is, an XI demonstrator kit in the United States is built and is available for viewing by appointment. Alternatively, Manik is working with several build partners who may have a completed car that is close to you, or can put you in touch with other owners of a Westfield XI. Manik will also be available to help you connect with a build partner closest to you. We are always available to help answer your questions as best we are able. Our build partners are committed to proper business practices and giving you the product you deserve.

        Q. Is the Westfield XI SCCA or NASA legal for Racing?

        A. Yes, the Westfield XI can be run in many racing forums. SCCA has a class for virtually any car that wants to run if it has the proper safety equipment. NASA will also accept the XI to race in certain classes.

        Q. What Is The Process For Purchasing My Westfield Kit?

        A. Manik Technologies has made it very easy to acquire a Westfield XI. Once you are ready to place your order, we will provide you with an order form and other pertinent details. Once we have received the signed order forms and a deposit, your kit order will be placed.

        Our pricing policy is simple - the price shown, plus delivery within North America, is the price you pay. Before your purchase, we will fully quote all delivery charges, something most companies in our business leave vague, or ask you to take care of.

        We are available to speak with you to help you with ideas, suggestions or explanations about Westfield products and your kit. Our staff is knowledgeable and will be glad to help!
