The steel used in the rotor blades is a special stainless blend with higher friction effect than normal heat treated stainless steel found on stock discs
Boasts up to 10% improvement in friction effect improving brakes even further
Weight of the X series is reduced by 5-10% by using a 6 button drive system on a lightweight alloy center hub which grabs the lead over stock parts
The SD-System of square sided buttons means that the rotor can expand inwards and outwards unrestrained and that perfect rotor functionality is retained at any speed or load
These units are riveted together and are no longer rebuildable due to the infinite service life obtained with the SD square drive button system
Universal left or right side application
