Performance Friction's Direct Drive Rotor Conversions are 2 piece replacements to the factory OEM rotor. They utilize the factory Caliper, so there is no extra hardware, brackets, or fabricating necessary.

Two piece rotors bring the benefits of increased cooling, better weight reduction and thus increased brake life and performance. These rotors benefit from extremely high quality manufacturing and will reduce thermal distortion and warping, reduce drag and increase your gas mileage, and offer No rattling - a 100% silent rotor. The Hat assembly is re-usable and replacement rotors are readily available. Because you still use the stock calipers, you can still use all your favorite brake pads.

The Details:

• High Carbon Alloy with copper and molybdenum for high temperature strength and durability.
• Vanes turned OD and ID for balance to reduce thermal warping and vibration.
• Runout less than .001 inches, reducing Pulsation and Vibration
• Thickness variation less than .0003 inches reduces Pulsation and Vibration.
• 47 or more vanes for superior thermal capacity
• Aircraft quality heat treated for micro structure alignment and durability.
• Surface finish less than .7 microns.
• 100% measured and inspected to meet tolerance specifications.

Note: You must use Performance Friction's rear pad #7855.01.16.44 with this rear application.

These are track pads that are to be used if you have the Performance Friction Direct Drive Rotor Kit installed on the rear of your BMW E46 M3. They come in 01 compound only, so be sure to use the 01 compound in the front as well.
