Performance Friction introduces a two piece floating rotor to work with your stock calipers and braking system!
- Made from High Carbon Alloy with copper and
molybdenum for high temperature strength and stability
- Vanes (all 47) are turned on both ID and OD
surfaces to reduce thermal warping and vibration
- Runout less than 0.0005" and thickness
variation less than 0.0002" to reduce pulsing and vibration
- Surface finish less than 0.7 microns
- Double-shear bobbin attachment to allow both
radial and axial expansion - far superior to BMW Motorsport rotors
Higher precision and tolerances give you a rotor
that will reduce drag, eliminate pulsation and vibration, and reduce heat
transfer. And, wear is increased as well! Two pounds per rotor lighter with a dimpled finish that performs similar to slotted discs but without the wear.
Direct Drive rotors require a higher initial
investment versus BMW Motorsport or floating rotors due to their superior
quality but the service cost of replacing the rotors are very similar. Please
refer to the Direct Drive replacement disc listing for prices.
We ONLY suggest Performance Friction
pads to work in conjunction with Direct Drive rotors*.

Includes fully assembled hat, directional rotor, and Direct Drive™ mounting hardware.
Prices are per SINGLE rotor. Replacement discs also available.
* Some aftermarket and OEM brake pad manufacturers
have a taller profile than Performance Friction pads. We have noticed these types of
taller profile pads becoming too close to the bottom of the friction area of the disc and can create a
stress riser causing premature fatigue of the disc. When cold, there must be 2mm
of space between the bottom of the pad and the bottom of the friction disc where
the fingers meat the friction area. As the rotor gets hot and expands this space
will diminish. To reduce the chance of this issue arising, we suggest only using
Performance Friction pads with Direct Drive rotors.
NOTES
- E46 M3 rear Direct Drive rotors require a Performance Friction 7855 pad
for mounting bolt clearance. This shape can be found in our PFC pad listings in street, street/track, and
100% track compounds.
- A very small percentage of E36 M3
cars are affected by on off-sized front hub assembly (143mm OD versus 139mm), presumably supplied by one
of BMWs suppliers with a different spec. PFC DD rotors will require
replacement of this hub with the standard sized part. SKF Bearings are correct at 139mm.
