Why upgrade
Some rear calipers are hard to find. This kit runs 370Z Akebono or Infiniti G37, Q60, Q70 rear calipers over 350mm rotors. That’s up from 258mm (S-chassis), 297mm (R-chassis) or 300mm (GTR).
The rotors are two-piece, with heat-treated T6-7075 aluminium hats. The pair is 1.94kg lighter than the factory 370Z 350mm rear rotors, which means less unsprung weight. The rings are vented and slotted, with curved slots to help keep the pad face clean.
What’s in the kit
- HFM.Parts 350mm two-piece rear rotors (pair)
- 350mm rear caliper adapter brackets for 370Z Akebono or Infiniti (pair), with bolts
Will it fit my car?
You’ll need 370Z Akebono or Infiniti G37, Q60, Q70 rear calipers and 18″ wheels or larger. Check the casting number on your caliper reads 4101.
S-chassis cars (S13, S14, S15, 180SX): convert to R-chassis rear 5-stud hubs, handbrake shoes and cables first.
The backing plate, knuckle and caliper need some trimming. See Fitting below.

Ready to fit
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.
Fitting
Clean the hub face. Grind off the backing plate tab and trim the outer edge of the backing plate to clear the larger rotor, or remove the backing plate entirely. If you keep it, cut out the section that meets the caliper.
The knuckle needs a cut of roughly 6–7mm for caliper clearance, and the caliper may need about 15 x 15mm removed so the bolts turn freely by hand. Take material off slowly and test fit often.
Fit the adapter with thread locker at 38–52 Nm (28–38 ft-lb). Fit the rotor, then the caliper with thread locker at the same torque. The 350mm rear brake kit install guide marks exactly where to cut.
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.
