 Pistons: OE specifications and specific Performance pistons for racing calipers.
๏ Performance dust boots: made of silicone material developed under our specifications, wont crack under very high temperatures.
๏ Performance piston seals: completely developed and formulated by FRENKIT, new seals offer more durability and confidence in extreme heat conditions than the standard components.
๏ Temperature strips: every kit includes a custom FRENKIT temperature indicator strip. It is applied directly to the brake caliper and indicates the maximum temperature achieved during use. This is fundamental to control the aging and performance of the brakes.
