Frenkit Performance Brake Caliper Seal Rebuild Kit - Nissan GT-R (R35) / BMW M2 Competition (F87) / M5 Competition (F90) / X6 M Competition (F96) - Front Brembo 6-Pot
This Frenkit Performance kit reseals one Brembo 6-piston front caliper with 30, 34 and 36mm pistons. It suits the Nissan GT-R (R35) with 380mm or 390mm front discs, BMW M2 Competition (F87, 6-pot), M5 Competition (F90) and X6 M Competition (F96).
Frenkit Performance kits use a high-temperature silicone dust boot and Frenkit's own seal compound, built for track days and hard road driving where standard rubber hardens and cracks.
Note: This kit services one caliper; order two kits for a pair. Check that your caliper is the 6-piston Brembo with 30/34/36mm pistons before ordering. Installation by a professional is recommended.
