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

The GKTech Caliper Bracket for the Nissan R33 GTS-T is designed to allow the use of the larger 324mm front rotors from the R33 GT-R, while retaining your factory 4-piston Sumitomo calipers. This upgrade significantly increases braking surface area and thermal capacity, improving stopping performance without the cost of a full big brake kit.

CNC-machined from 6061-T6 billet aluminum and anodized for corrosion resistance, these brackets bolt directly to the factory knuckles, spacing the caliper outward to suit the larger rotor—making it a bolt-on solution with no cutting or welding required.
