Requirements
Why upgrade
The R32 GTR runs 296mm front rotors. This kit steps you up to 324mm, 28mm larger, and keeps your factory calipers. It’s an affordable big brake upgrade: more rotor for better heat dissipation and braking, with no new calipers to buy.
What’s in the kit
324mm front rotors (pair). Choose single-piece, or two-piece to save weight.
Single-piece rotors have a clean, slotted face. The slots have a slight curve to help keep the pad surface clean and improve ventilation. The hub is painted black for rust resistance.
Two-piece rotors weigh 7.4kg each, 1.5kg less per corner than our 8.9kg single-piece rotors. The ring is free to expand and contract as it heats and cools, and the centre hat is heat-treated T6-6061 aluminium.
Caliper adaptor brackets (pair). T6-6061 hard anodised billet aluminium with stainless steel Heli-Coils, supplied with M12 caliper bolts. They space your calipers out to suit the larger rotor.
Ready to fit
Single-piece: Every rotor is runout tested and balanced before it leaves us, so it’s a direct bolt-on straight out of the box.
Two-piece: Two-piece rotors arrive with the hat and ring already bolted together, runout tested and balanced as an assembly. Always check the hat bolts are at 13–15 ft-lb before fitting, as you would with any two-piece rotor. Otherwise, it’s a direct bolt-on.
Will it fit my car?
R32 GTR: bolts up with your factory front calipers.
R32 GTS-4: the factory GTS-4 calipers are smaller than the GTR calipers, so fit R33 GTS-T front calipers first.
The brackets are designed for factory Nissan calipers only: R32 GTR or R33 GTS-T, not Brembo. We can’t confirm fitment with aftermarket calipers. You’ll need 17″ wheels or larger.

Fitting
Remove the rotor and caliper. Linish a small area of the knuckle until the lower bolt hole of the bracket lines up. You may need to trim or remove the backing plate so the larger rotor clears. Mount the bracket on the inside of the knuckle with the two factory hex head bolts, refit the rotor, then bolt the caliper to the bracket with the supplied M12 hex head bolts. Torque all bracket and caliper bolts to 60–70 ft-lb (81–95Nm). Brackets are marked HFMGTR32/LH and HFMGTR32/RH.
With the caliper spaced out, check your brake lines reach without strain. Fit longer lines if they’re at full stretch.
Step-by-step photos are in our R32 GTR adaptor bracket install guide.
Rotors are non-directional, so either rotor can go on either side. On two-piece rotors, check the hat bolts are at 13–15 ft-lb before fitting.
We recommend installation by a licensed mechanic.

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.
