StopTech 83.137.4700.71 Big Brake Kit Front Slotted Rotors 01-07 BMW M-Series M3 E46
Big Brake Kits give your vehicle that Supercar look and feel and exceed stock performance in two areas. First larger rotors increase heat capacity. Second stiffer calipers and stainless steel lines reduce system compliance.
The key however is to increase heat capacity and reduce compliance without upsetting the stock front to rear brake torque ratio. If the brake upgrade you select adds too much front torque (as many do) you reduce your car's ability to utilize the tractive capacity of all of the tires to the maximum practical extent (even on ABS equipped cars) and you therefore create performance sacrifices. In addition too many pistons or pistons that are too large will make the brake pedal much more difficult to modulate which limits a driver's control of brake input on the race track.
