Recently released by Kneibler Autotechnik is their version of the BMW E46 M3 Coupe with some increased performance and an interesting wheel package. Under the hood the car tuning company offers a supercharger using a compressor kit, and a charge air cooler with adequate software to optimize the setup. The supercharger performance upgrade for the BMW M3 E46 Coupe was installed by the famous tuning firm G-POWER, and the supercharger is from ASA TurboMex. These performance improvements are priced at 13,000 euro, and for an additional 1,350 euro, Kneibler Autotechnik will mount a sport exhaust made from high quality steel. After the complete tuning kit is installed, the BMW E46 M3 has final output figures of 459 hp and 498 Nm of torque.
These new performance numbers bring great demand on the brakes, tires, and chassis, so Kneibler mounted a StopTech high performance brake system with 6-pistion calipers and slotted rotors in the front. The rear of the car received 4-piston calipers and the same slotted discs, with pricing at 3,852 euro for the front, and 3,103 euro for the rear. Complementing the new brake system is an innovative brake caliper air vent plug from Stahlbus, which sells for 109 euro.
In the four corners are Oxigin-alloy wheels that really enhance the visual appearance of the vehicle, however are not the wheels I would choose for my BMW M3 if given the chance. Even though they do fill out the fender perfectly, giving that clean flush look that every tuner desires. The rims measure 20×8.5 and 20×11, and come wrapped in high performance tires from Hankook, which measure 255/30/20 in the front, and 305/25/20 in the rear. The price for the wheel package from Kneibler Autotechnik is 2,723 euro, and for an extra 350 euro the wheel arches are flanged and custom-fitted. The final modification installed on the BMW E46 M3 Coupe is a KW-sport coilover kit for 1,749 euro, and also available are the KW-sport stabilizers for an extra 419 euro.
