BMW M3/M4 & M5/M6 (F10 & F90) Rebuild Kit for Front Calipers (Price is for 2 Calipers) Gold Calipers

These stainless steel pistons are excellent upgrade from your stock aluminum pistons, not only they are stronger and more rigid than aluminum, they will not corrode and can transmit more brake torque but with less heat (about 1/10) than stock aluminum pistons. Our pistons also have vents to further prevent heat transfer to fluid, allow you to run your brake system at lower temperature which means less replacement on brake fluid, and eliminate the use of titanium shims saving you down time, operating and maintenance cost.

This kit includes the following to rebuild two complete calipers: 12 Pressure seals 12 Dust boots 12 Stainless steel pistons High temperature (450F) boots (Blue) made of Silicon, Extreme caution must be exercised to avoid those high temp boots in contact with brake fluid,
