Body

The Superformance MKII FIA bodywork replicates the European FIA regulated form but is here produced in fiberglass. While every one of the FIA cars differed in some small way from the others, one of the identifying characteristics were the different colored stripes painted across the fenders and hood of the Team Shelby cars.

The Superformance MKII FIA features the larger Le Mans type fuel filler placed almost directly behind the passenger’s seat to enable easier pit refilling. Just like the originals, cars may also be fitted with a small wind deflecting shield to prevent fuel being sucked out and into the car at speed.

More fuel was required in the endurance-racing FIA cars, so a special long-range fuel cell was fitted in the trunk. Because the FIA required there be enough room in the trunk for a regulation size suitcase as well, two dimples had to be "engineered" into the boot lid for it to close properly. Legend has it that the first dimples were actually created when the aluminum trunk lid was slammed shut over the luggage by a frustrated mechanic. The reserve fuel switchover valve has been placed on the floor between the driver's legs just in front of his seat.

The hood of the Superformance MKII FIA also gets special treatment. The rivets that appear on the front of the hood were there to prevent the aluminum from being torn off of its frame at high speed. This was known to happen on the originals, due to the high pressure build-up in the engine compartment. The fender air vents helped to alleviate that problem and to remove excess heat from the engine compartment as well. Fiberglass air scoops are also fitted in three locations to feed cold air onto the front and rear brakes as well as into the cabin foot wells.  

Because of the use of larger tires on the FIA cars, the rear and doors were modified to accommodate them. Cut back doors and a more bulbous rear appeared, and the front fenders were flared even further to cover the larger front tires as well. Oil coolers for both the motor and differential have been fitted. Rondel illuminating lights were fitted on the sides of some of the originals for night racing and are available here as well. A roll bar has also been fitted with a forward angled support tube brace bolted to the chassis in the passenger’s foot well. No carpets were fitted and all other trim was also removed.

Suspension

To compliment an original chassis you need to follow the same rules when it comes to the suspension. It had to be period correct, or as close as possible. The original slab side had a transverse leaf spring style suspension which requires different length springs to change camber settings we decided to use heim joints which were used on some of the original competition cars.

Another change with regards to safety was to add an additional pick-up point to the chassis to increase the shear strength of the bolt passing through the lower control arm rose joint or poly-bushed rod end. The original springs were made of thinner steel than that available today. In an effort to keep compression rate the same, this car comes with one blade less and “free camber” was changed to keep the ride heights equal from front to rear. This insistence on authenticity means that owners of a Superformance MKII Roadster will have virtually the same driving experience as the original.
