BMW Drilled & Slotted Brake Rotors for BMW E36 (1992-1998) M3

Cross-drilled rotors are a quick and simple way to improve initial pad bite. With the additional leading edges at each hole, the pad is able to grab the rotor just a little bit harder when itaEURtms time to stop NOW! Tests have shown (and drivers can feel) the immediate improvement. The holes also provide better cooling under hard use. Pad wear may be accelerated slightly (depending on driving technique), so only high quality brake pads should be considered.

Slotted rotors provide much of the increased pad bite that cross-drilled rotors do, but can handle the heat of more aggressive use. The slots act as a wiper, cleaning the pad face as they go by to reduce pad glazing, keeping the pads fresh for optimal performance. If taking the car often to track days or where very spirited driving is the norm, slotted rotors are the smart choice.

Cross-drilled and slotted rotors combine the best of both. Fewer holes mean longer pad life with little penalty in the way of initial pad bite. These are popular, aggressive-looking patterns that look great behind custom wheels.

Every SportStopA(r) rotor is finished with black e-coating on both sides of the hat, inside the the cooling vanes, and on the outside edge. E-coating is a superior electro-statically applied finish designed to withstand 400 hours of salt water exposure without rusting. This is especially important on both mounting faces of the hat where it touches the hub flange and back face of the wheel. Any accumulation of rust in these area can lead to installed lateral run out issues.
