17Z/18Z Big Brake Conversion Kit - E46 & E9X M3

Regular price $2,300.00

Introducing our 17Z/18Z BBK conversion kit, applicable to both E46 and E9X M3 platforms. This big brake kit conversion utilizes the brake components from the Porsche Cayenne (957+) and provides a massive brake upgrade to the lackluster factory brake setup found on E46 and E9X M3s in both performance and aesthetics. 

The calipers themselves are fully refurbished while all the other components included in the kit are brand new.

  • Front and rear calipers
