Performance Friction Direct Drive two Piece Floating brake rotors Porsche 996 GT3- 997 GT3/GT3RS Front 380 mm

Performance Friction V2 Direct Drive rotor assemblies and replacement discs are replacements for Performance Friction big brake kits only. Replacement disc (friction ring)  has the option of including new mounting hats (shipped assembled). Direct Drive rotors are 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. This is the only rotor that is mechanically, thermally, and dynamically balanced - meaning you will never warp them because they are balanced in all situations, all temperatures. New V2 design reduces weight an additional half pound from the already light V1 components.

Features:
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.
Thickness variation less than .0003 inches and Run out less than .001 inches reduces Pulsation and Vibration.
47 or more vanes for superior thermal capacity.
Aircraft quality heat treatment for micro structure alignment and durability.
Surface finish less than .7 microns.
100% measured and inspected to meet strict tolerance specifications.
Made in the USA
