BRAKE DISC 7.5" GROOVED COMPETITION BRAKE DISC

 

A common complaint of standard issue Cooper S brake discs is that they wear too fast.

The wear is caused by grit getting caught under the pads, and is amplified by the fact that the discs are made of too-soft material.

These heavy duty, competition discs are of a higher grade steel, but more importantly, feature grooves machined into them on both sides that serve to clean the pads and discs, further increasing their life expectancy.
