A peak output of 414hp (308kW) almost matches that of the V8 powered M3
The first impression you get of the car is its lower, more aggressive stance courtesy of a suspension kit consisting of new custom-valved Bilstein struts, stiffer springs and anti-roll bars. The vehicle now sits 25mm lower in the front and 20mm lower in the rear, providing a more stable ride. Filling the fenders are lightweight, 20in RD2 Monoblock wheels or the optional 20in RS2 multi-piece wheels shod in P Zero Nero's supplied by Pirelli.
Engine performance includes electronic modifications to increase boost and optimize fuel and timing. A free-flowing intake and a larger, more-efficient intercooler help supply enough air. Exhaust gasses run through a larger exhaust that terminates in stainless sport silencers with quad tips. These modifications result in an increase in horsepower and torque to 414hp (308kW) and 404lb-ft (547Nm) – almost on par with the V8 powered M3 in terms of power.
The front of the vehicle is finished with a blue engine cover sporting an RDSport crest. Revised bodywork is also a large part of the car, and a custom carbon-fiber front bumper offers larger openings for better engine and brake cooling. Deeper side skirts and a revised rear apron with quad exhaust cut outs add to the aggressive look, while a roof and trunk spoiler smooth out the airflow over the car.
Interior upgrades include the RS Pedal Set in machined aluminum, an aluminum hand brake cover and custom floor mats.
