Kraftwerks has taken the core components of the extremely popular RACE Supercharger Kit and added redesigned supercharger mounting brackets, wider drive pulley set, and a more robust 30mm belt. The wider belt is 57% stronger than our previous offering, making the new kit the most reliable and best-performing supercharger on the market! Performance and reliability are what you get with Kraftwerks!. Like all Kraftwerks supercharger systems, the Subaru BRZ, Scion FR-S, and Toyota FT86 supercharger system includes all the necessary brackets, and hardware for a simple bolt-on installation.
