BMW M2 CS CCB Brake Caliper Dust Boot Set High Temp Silicon

The BMW M2 CS CCB Brake Caliper Dust Boot Set — High Temperature Silicon is a performance-grade set of six grey silicon caliper piston dust boots for the F87 M2 CS Carbon Ceramic Brake (CCB) front caliper — designed for BMW M2 CS owners who use their car on circuit regularly and require dust boot material that withstands thermal conditions beyond the OEM rubber specification's range. One package covers one front caliper.

OEM vs. High Temp Silicon — Which Do You Need?

The OEM rubber dust boots (Part No. 34117845750) are BMW's factory specification and are correct for road use and occasional track days. For M2 CS owners running multiple track events per season — particularly long sessions, endurance events, or back-to-back lapping — the thermal cycling through extreme temperatures at the caliper face repeatedly stresses the OEM rubber beyond its optimal range. High-temperature silicon retains its elasticity, sealing properties, and structural integrity at sustained elevated temperatures that degrade conventional rubber. The silicon boots offer greater longevity under track thermal conditions and reduce the frequency of caliper dust boot maintenance intervals for high-use track cars.

Key Benefits

• High-temperature grey silicon — superior thermal resistance vs. OEM rubber specification
• Set of 6 piston dust boots — covers one front caliper
• Engineered for M2 CS CCB six-piston front caliper (Gold caliper)
• Maintains sealing properties through sustained high-temperature track cycling
• Extended service life under intensive track use vs. OEM rubber alternative
• Recommended for: regular track drivers, endurance events, multiple-session track days
