To take the concept due to the unfavourable, as top-heavy weight distribution of the M3 in combination with the resulting from the rear-wheel drive traction problems concern, a chassis developed a workx together with suspension specialist KW for the M3, which was quite specifically matched to the characteristics of this vehicle. This week-long test work with professional racers and chassis engineers was necessary until Niko Wieth was finally satisfied with the result. The combination of ride height, the weight distribution on all four wheels (wheel loads), track and fall values, the correct spring and damper rates and the exact setting of tensile and compression is ultimately responsible to the maximum ground contact of tire and therefore optimum traction and achieving the best possible grip. You can well imagine, that a such a sensitive vote of the suspension by the mounting harder Wheels can be made quickly lost. Therefore the record light 19 are on the M3 460 cs ATS Superlight weighs 7.9 kg (series rim 10.2) mounted. Of course, the performance remains not untouched. The heart of the performance is an Akrapovic evolution exhaust system with special catalysts.
It is made of high-strength and super-light titanium, which positively affects the weight balance with a 25 kg weight reduction. In addition, special camshafts installed, conducting intake air with carbon airbox and sport air filter improves, and tuned the engine electronics on the changed parameters. What comes out is simply sensational: the M3 460 cs now has a performance advantage of 40 HP and 460 nm of torque (series 400 nm) depends directly on the gas as the nervous system of the driver directly to the throttle would be connected. The motor turns completely harmoniously to 8,500 rpm, before exhorting the button lights to train at the rocker switch. The weight reduction of more than 70 kg in connection Let the M3 cs 460 in 4.1 s 0-100 and 13 with the performance, Sprint 2 s 0-200 (series 15.7 s). But there’s the best part: only on winding route, one notices the true qualities of the stricter 3ers. He directs a smart, pants almost after the next bend and put exciting and completely neutral to any kind of bending. You can feel literally like perfect chassis and excellent Michelin pilot sport Cup harmonize with each other and build maximum mechanical grip.
The reduction of the rotating, unsprung masses benefit from this and let even the comfort component not to be neglected. Ceramic brakes is still one the whole on top. These bites as there no tomorrow. Good that the pilot in the 7.4 kg lightweight Recaro pole position seats is fixed. The vehicle is pure emotion and fun. Alone, to let the eye about the noble components made of titanium, aluminum, ceramic and carbon hiking and to be sure to have only the best of the best on is the Been worth the investment. However, the cream of the crop of a-workx M3 is the sound, the fine Akrapovic evolution titanium exhaust system which elicits high speed V8. This can raise the hackles, while at the same time, a broad grin on the face casts. As said, sheer driving pleasure!
