5:1 - 193.72 Km/h
Single dry plate power assisted clutch, Ø240mm.
Cam Gears/TRW rack and pinion steering, 2.45 turns lock to lock, variable power assistance.
|Suspension||Front: Independent McPherson struts lower control arm, coil springs and ProFlex 2-way adjustable gas shock absorbers with remote nitrogen gas reservoirs, urethane bushes, 28mm antiroll bar. Spring rate: 70KN/m Spring length: 270
Rear: Independent transverse arms, relocated (coilovers) coil springs and ProFlex adjustable gas shock absorbers with remote nitrogen gas reservoirs, urethane bushes, 22mm antiroll bar. Spring rate: 36KN/m Spring length: 320
Shocks are separately adjustable for compression/rebound in 21 positions. Currently using 12 "clicks" for rebound and 10 for compression at the front, 11 "clicks" for rebound and 7 for compression at the rear. The ride height is also adjustable.
Altered suspension settings with increased front and rear negative camber. The front wheels use a slightly negative parallelism.
|Brakes||Front: AP Racing vented floating disks (330 mm and aluminum bell) 4 pot fixed aluminum AP Racing calipers, Mintex 1144 pads. Forced air induction for brake cooling.
Rear: AP Racing vented floating disks (315 mm and aluminum bell) 1 pot floating calipers, carbon-metallic pads.
Teves ABS (5 sensors) switchable.
Stainless steel braided Teflon hoses are used throughout. The front brakes use add-on ducts for forced cooling.
|Chassis||Monocoque steel construction.|
|Wheels/Tires||8"x17" Compomotive MO wheels, Pirelli pictureP Zero C 235/45ZR17|
Front track: 1496mm
Rear track: 1515mm
Laden weight: 1280Kg (air conditioning removed)
|Performance (works)||0-100Km/h acceleration: 4.1Sec
Max speed: 200 Km/h
0-1000m acceleration: 24Sec
|Miscellaneous||K&N air filter. Reinforced chassis with front and rear strut braces. Additional switch to set a 0.8 Bar max turbo pressure (for reliability reasons)|
|Notes||The car has been developed with s focus on drivability and point to point performance rather than sheer power and acceleration figures.
Compared to the stock version the car is a real joy to drive. No brake fade whatsoever, very low turbo lag time, none with the ALS switched on, lots more power and torque. It can obliterate almost anything on track or open road. More than the sheer acceleration it's the car's road holding abilities that are simply amazing. The close ratio gearbox allows a much easier exploitation of the engine. The stainless steel exhaust is a lot lighter and much less restrictive than the OEM one but very noisy.
