Product Description
Replacement rotor ring for E36 M3 V3 rotors. This is a replacement LEFT side friction ring only - you must already have the V3 hat and ring assembly to use this disc.Performance Frictions higher precision and tolerances give you a rotor that will reduce drag, eliminate pulsation and vibration, and reduce heat transfer. Plus, wear rate is greatly reduced as well! Direct Drive V3 rotors are over two pounds lighter per rotor with a dimpled finish that performs similar to slotted discs but without any increase in wear.
- 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 of less than 0.0005" and thickness variation less than 0.0002" to reduce pulsing and vibration
- Surface finish less than 0.7 microns
- Advanced V3 two-turn retaining ring
