2009 RDSport BMW RS35 Biturbo

(from RDSport Press Release)  For those wishing to increase the performance of an already stellar platform, RDSport offers the RS35 Biturbo.

The first impression you get of the car is its lower, more aggressive stance courtesy of a Chassis Kit consisting of new custom-valved Bilstein struts, stiffer springs and anti-roll bars. The vehicle now sits 25 mm lower in the front and 20mm lower in the rear with a decidedly more stable ride. Filling the fenders are lightweight, 20 RD2 Monoblock wheels or the optional 20 RS2 multi-piece wheels, shown. Tires are P Zero Neros supplied by Pirelli, our development partner.

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 414 bhp and 404 lb/ft more than the V8 powered M3!

The under hood area is finished with a blue engine cover with RDSport crest. These numbers are merely the result of a long development period including TUV homologation. Any tuner can offer a black box upgrade for the vehicle, but how many can say that their modification has been tested and can include the upgraded speedometer and wheels and tires that the homologation requires.
Bodywork is an evolution of RDSports signature Tornado aerodynamics. The revised carbon front bumper offers larger openings for better engine and brake cooling with an exposed carbon housing for fog lights. Deeper side skirts and 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, aluminum hand brake cover, logo carpet set, the aforementioned upgraded speedometer with logo and RDSport crests in the steering wheel and shift knob.

Each complete vehicle built by RDSport includes a vehicle ID badge and VIN specific build sheet.
