C4 Stainless Steel caliper pistons $129.95
The factory aluminum pistons are a huge heat sink, rapidly transmitting heat from the pads into the fluid. DRM’s stainless steel pistons insulate the fluid resulting in a more consistent brake pedal and less chance of fluid boil. When high performance or racing pads are used these pistons are considered a must.
