GrimmSpeed 4-Piston Brake Caliper Kit - Subaru BRZ (ZC6/ZD8) / Toyota GR86
GrimmSpeed built its name on developing genuine performance upgrades for the Subaru platform, and this fixed 4-piston caliper kit is a purpose engineered answer for owners who've outgrown the factory single piston setup. It bolts up to your Subaru BRZ or Toyota GR86 without hunting down used Brembos or fabricating custom brackets.
This listing covers the Subaru BRZ (ZC6/ZD8) and Toyota GR86 (ZN8), running the factory 326mm rotor. The kit is available in Red or Gunmetal Gray anodised finishes — select your colour from the variant options on this listing.
Note: This kit is designed around OEM-style hubs and rotors, so no knuckle swaps or custom adapters are required. Confirm your existing rotor matches the 326mm specification before ordering.
