System Description
Outline
Double wishbone independent suspension has been selected for each of the four wheels. This eliminates damper friction
along the steering axis and permits suspension geometry that takes full advantage of the performance potential of the
wide, low aspect ratio tires. The double wishbone design also allows the use of aerodynamically-efficient and
aesthetically pleasing low fender lines.
The knuckles and the suspension arms are manufactured from light-weight, high-strength aluminum alloys. This gives a
notable reduction in unsprung weight which results in increased traction and improved ride. It also allows the individual
suspension components to be designed in detail for maximum strength and rigidity.

To further increase suspension link rigidity and to obtain optimum knuckle geometry, the knuckles and ball joints are con-
tained within the wheel profile. At each corner of the car, the individual suspension system is attached to the aluminum
stressed skin chassis by a cast aluminum sub-frame. This design further reduces overall weight and ensures that suspen-
sion loads are fed into the chassis at the most efficient points and in the most efficient directions.
A large front caster angle combined with small trail distance improves straight-line stability and response without caus-
ing heavy steering effort.
