GKTech Nissan HFM R33 GTS-T caliper bracket to suit 324mm R33 GTR rotor

The GKTech HFM Caliper Brackets allow you to upgrade your R33 GTS-T’s front brakes by fitting larger 324mm R33 GT-R rotors while retaining your factory 4-piston Sumitomo calipers. This bracket relocates the caliper outward to accommodate the larger rotor diameter, giving your braking system a significant boost in thermal capacity and stopping power—perfect for street, drift, or track builds that need more without the cost of a full big brake kit.

Made from CNC-machined 6061-T6 billet aluminum and anodized for durability, these brackets are a true bolt-on solution that installs using factory hardware.
