I pulled the BBK off the i30krab, and with the help of Victor Dragos we identified it as a Brembo GT JR big brake kit, using 2-piece Brembo 13″ rotors. These rotors were commonly used on VW, Porsche, and Audi applications.
- Calipers & Adapter: The calipers are radial mount, and a Brembo-marked adapter (with part and serial number visible in the pics) was used to fit the Nissan application. The caliper mounting holes are 130mm apart. The adapter bolted up with no modifications to the knuckle.
- Fitment Mods: The brake dust shield had to be removed for clearance. Steel braided brake lines were also added.
- Wheel Fitment: On the i30krab, the kit cleared 17″ Volk wheels. On my current setup, 18″ wheels with +35 offset clear with room to spare.
- Caliper Work: I painted the calipers with two layers of G2 epoxy paint. I actually split the calipers during the process (not really recommended). While doing that, I had to replace the separator O-ring for the brake fluid transfer port. I lost one and ended up sourcing replacements — New Provisions Racing O-rings for 2004–2017 STI Brembos worked perfectly.
Overall, this is a great kit. I’m still researching more details since some info I gathered came from old sale posts, so specs may vary slightly depending on the exact kit.
