Product Description
This 372mm left front slotted brake rotor assembly is a replacement part for the Performance Friction Z54 front big brake kit on E90/E92/E93 M3 (2008-2013) and E82 1M (2011-2012).This Performance Friction brake rotor is the newest design of PFC V3 Direct Drive Rotors. Made from a precision casting, all external surfaces are machined to tolerances of 0.004", including the OD of the vein area that most manufacturers leave rough-cast. These are the only rotors that are mechanically, thermally and dynamically balanced, which means you will never warp them because they remain balanced in all situations and at all temperatures. Not only does the V3 design give you the ability to change a disc quickly and efficiently, the new V3 technology also makes these rotors much lighter than previous designs, which were already impressively light - less unsprung weight is always a good thing! This V3 rotor retention method is based on the use of a two-turn retaining ring, which is held in a groove in the hat that overlaps the rotor flanges—effectively locking the rotor to the hat.
