Requirements
Bigger rotors, R33 GTS-T calipers
These brackets move R33 GTS-T or R34 GT front calipers outward so they clear our 324mm front rotors, the same size as the R33 and R34 GTR. A larger rotor spreads heat better and improves braking, and you keep the calipers you already have.
They’re machined from T6-6061 billet aluminium, hard anodised, with stainless steel Heli-Coil inserts in the threads for strength.
Will it fit my car?
These brackets suit the factory R33 GTS-T and R34 GT front calipers. They bolt to the R33 GTS-T and R34 GT, and to an S14, S15 or R32 GTS-T that has been converted to R33 GTS-T or R34 GT calipers. An S13 running R33 GTS-T calipers also works with 5-stud hubs and knuckles. You’ll need 17″ wheels or larger.
- Still on factory S14, S15 or R32 GTS-T 4-piston calipers? Use our 324mm adapter brackets for S14, S15 and R32 GTS-T calipers.
- R34 GTT? Use the R34 GTT adapter brackets.
- R32 GTR or R32 GTS-4? Use the R32 GTR and GTS-4 adapter brackets.
- Want rotors and brackets together? The 324mm front brake upgrade kit for R33 GTS-T and R34 GT calipers includes these brackets.

Fitting
The brackets are marked 324R33_L and 324R33_R for each side. Remove the factory caliper and rotor, then remove the backing plate or trim back its outer edge to clear the larger rotor. Fit the bracket to the inside of the knuckle using the factory hex head bolts, then finish with the supplied M12 x 1.25 x 50mm hex head bolts, spring and flat washers. Follow our install guide.
We recommend installation by a licensed mechanic.
Pairs with
- HFM.Parts 324mm front brake rotors: single or two-piece, sold as a pair.
- Front braided brake lines for R33 GTS-T and R34 GT / GTT: slightly longer than standard to suit the bigger rotor.
Brake Line Selection:
S-Chassis = S-Chassis Front Lines
R32 GTS-T = R32 Front Lines
R33 GTS-T/R34 GT = R33 Front Lines
*You will need extended brake lines to use this caliper adaptor due to the increase in rotor dimension.

Our Story
We weren't always HFM.Parts; we were Holford Motors. Our brand's identity was forged not in an office, but on the local circuits in the high-stress world of competitive drifting. Our ultimate testbed was our Nissan S14 Drift car, driven by champion Luke Fink. Pushing that car to its limits exposed a crucial truth: achieving genuine, repeatable performance meant relying on components that simply weren't available affordably on the market.
The HFM.Parts brand was born
We made the commitment to design and manufacture the uncompromising, high-quality performance parts that we, as competitive racers, demanded ourselves. Every component you see is a solution conceived, tested, and proven by us. When you choose HFM.Parts, you are investing in components engineered by racers, for racers, ensuring your vehicle delivers its maximum performance potential.
