Transmission and suspension
The Evolution is equipped with a 6-speed manual transmission manufactured by Porsche and mounted longitudinally on the car. The car uses double wishbone suspension on the front and rear axles, with coilover springs that allow for adjustment of bump, rebound, and ride height.
Chassis
The car's chassis is a tubular steel space frame panelled with 5251 aluminum alloy, and has a built-in roll cage for structural rigidity and safety. The car's body is made out of glass-reinforced plastic, with optional carbon fibre wing mirrors and front splitter.
Wheels
The Evolution is equipped with 18-inch (460mm) forged alloy wheels with an optional 19-inch (480mm) upgrade available. The tyres are manufactured by Michelin with codes of 245/35 for the front and 335/30 for the rear. The brakes are vented discs, with a diameter of 323mm (12.7in) at the front and rear.
Interior
The Evolution's seats and dashboard are finished in leather and Alcantara depending on the selected options. In place of a center console, the Evolution features a large, stainless steel gear lever and handbrake. The in-car entertainment system and optional satellite navigation system are manufactured by Alpine Electronics.
