Kit car automobile that the buyer assembles into a functioning car

A kit car is an automobile that is available as a set of parts that a manufacturer sells and the buyer then assembles into a functioning car. Usually, many of the major mechanical systems such as the engine and transmission are sourced from donor vehicles or purchased new from other vendors. Kits vary in completeness, consisting of as little as a book of plans, or as much as a complete set with all components to assemble into a fully operational vehicle such as those from Caterham.

The term "Indy" comes from the independent rear suspension which in its design was cutting edge at the time of inception.

The vehicles models can be identified in the following differing characteristics;

Indy - This is the original iconic design which features outboard front shocks and a square box section space frame chassis. Based on the Ford Sierra, this model used the steering rack, front uprights, steering column, diff, driveshafts and rear uprights from the donor car.

Indy R - Designed for the road and track, this model designed in 2008 using CAD simulation features inboard push rod front suspension and a combination of rounded and square tube for the space frame chassis. Based again on the Ford Sierra, this model also uses the same donor parts as the Indy.

Indy RR - Designed for the race track, this model is the inboard front suspension Indy R model, but differs by having fully rose jointed wishbones for granular adjustments for camber, caster and toe. This is also based on the Ford Sierra.

Indy RX-5 - The latest model in the range, this model was CAD designed in 2017 by Dave Flavell. Based on the Mazda MX-5 or Miata, this model uses all the running gear from the Mazda. The RX-5 features inboard front suspension and a space frame chassis constructed of rounded and square tube. Designed for the road and track, this model uses poly bush fixings for the wishbones rather than the rose joints of the Indy RR. Out of the box, this model boasts 6 degrees of caster and coupled with a 2.4 turn lock to lock "quick" steering rack, a very adequate feel on the tarmac.

Dimensionally, all models are the same and share the same fibreglass bodywork panels, however, the suspension and donor vehicles make each of the models unique.

Ford GT40 high-performance endurance racing car

The Ford GT40 is a high-performance endurance racing car with the Mk I, Mk II, and Mk III model cars being based upon the British Lola Mk6, and were designed and built in England, while the GT40 Mk IV model was designed and built in the United States. The range was powered by a series of American-designed and built engines modified for racing. The GT40 won the 24 Hours of Le Mans four consecutive times, from 1966 to 1969, including a 1-2-3 finish in 1966. In 1966, with Henry Ford II personally in attendance at Le Mans, the Mk II GT40 provided Ford with the first overall Le Mans victory for an American manufacturer, and the first victory for an American manufacturer at a major European race since Jimmy Murphy's triumph with Duesenberg at the 1921 French Grand Prix. The Mk IV GT40 that won Le Mans in 1967 is the only car designed and built entirely in the United States to achieve the overall win at Le Mans.

Double wishbone suspension Automobile Suspension

In automobiles, a double wishbone suspension is an independent suspension design using two wishbone-shaped arms to locate the wheel. Each wishbone or arm has two mounting points to the chassis and one joint at the knuckle. The shock absorber and coil spring mount to the wishbones to control vertical movement. Double wishbone designs allow the engineer to carefully control the motion of the wheel throughout suspension travel, controlling such parameters as camber angle, caster angle, toe pattern, roll center height, scrub radius, scuff and more.

Parts needing modification are the propshaft, which needs to be shortened, and the alternator that needs to be repositioned.
