The rim is available in the sizes 8.5 x 19, 10 x 19 and 11 x 19, weighs 10.5 to 12.4 kg only whilst still being extremely strong. It guarantees improved, safer driveability thanks to lower unsprung mass. The elegant, sporty 10 spoke wheel satisfies even the highest design demands.

Fine-tuning electronics in combination with an expanded air intake system, a carbon air-filter case, Sportec turbo chargers K24.700, sports camshafts, modified valve timing and fuel system, an exhaust with sports catalytic converter and a high performance clutch – these are the secrets of the SP580’s outstanding performance. The 3.6 l bi-turbo engine reaches an output of 580 HP at 6900 rpm, a plus of 160 hp (119 kW) in comparison with the series model. The torque has gained 125 ft lbs (170 nm) and goes up to 730 Nm at 4200 rpm. The vehicle is fully approved and fulfils the Euro 3/D4 exhaust guidelines.
Performance

This extreme performance requires extensive modification of the chassis frame. It is equipped with Sportec sport absorbers, with a special progressive spring set and its height is adjustable up to 35 mm. In cooperation with the manufacturer Continental, a special tyre has been developed to meet the requirements. The Sportcontact 2 Vmax guarantees maximum adhesion in extreme driving conditions as well. Front- and rear axle dispose of a high performance braking system.
