Match the bracket to your caliper and rotor
Each bracket is machined for one caliper and one rotor diameter, and both are in the product name. Pick the caliper first, then the rotor size.
- Factory calipers: 324mm fronts for the R32 GTR, R34 GTT, and S14, S15 and R32 GTS-T 4-piston calipers, plus 337mm rears on the factory Sumitomo caliper and 300mm rears for the S-chassis.
- Swapped calipers: 354mm fronts for 370Z Akebono, Infiniti or Kia Stinger Brembo calipers, 340mm rears for 350Z Brembos, and 350mm rears for 370Z Akebono or Infiniti G37, Q60 and Q70 calipers.
- Wilwood calipers: 324mm for the Silvia and 350Z, 326mm for the 86 and BRZ ZC6 and ZD8, and 280mm for the MX-5 NA and NB.
How they are made
Our adapters are billet T6-6061 aluminium, anodised, with stainless steel Heli-Coil thread inserts so the threads hold up to repeated fitting. Most come as a pair with mounting bolts. The 86 and BRZ adapter packages also include braided lines, so you can source calipers and rotors locally.
Check the rest of the setup
Brackets are sold without rotors unless listed. Get the matching rotors, check the minimum wheel size on the product page, and consider a complete brake kit if you need everything.
