Overview

Why upgrade

These are the adapter brackets from our 354mm front two-piece brake upgrade kit for the R33 GTR. They move your factory front caliper out to suit our 354mm front two-piece rotors, so you get a bigger rotor without buying new calipers.

Each bracket is machined from T6-6061 billet aluminium, hard anodised, with stainless steel Heli-Coils in the threads.

Will it fit my car?

These brackets are sold as a replacement part for our 354mm kit. They only work with our 354mm front rotors and need 18″ wheels or larger. Starting fresh? The full kit includes rotors, brackets and braided lines.

The brackets use M12 bolts to suit the R33 GTR knuckle. The R34 GTR knuckle uses M14, so they only fit an R34 GTR running R33 GTR front calipers.

We have only confirmed fitment for the vehicles mentioned under compatibility. If your vehicle is not listed, then we don't know if it fits.
The R33 and R34 GTR use the same front rotor size and caliper, but the caliper mounting holes in the knuckle are different: M12 on the R33 and M14 on the R34. Our adapter brackets use M12 bolts and holes. If your R34 GTR is running R33 GTR front calipers, the kit will fit.
No. They're made to position the caliper for our 354mm front two-piece rotors.
Yes, a little. The kit spaces your factory caliper out to suit the larger rotor, and the pads follow. We've kept overhang to a minimum: expect around 1.5mm with factory-size pads. We're not aware of a pad that fits the factory caliper and covers more of the rotor.
Any pad made for the factory R33 GTR front caliper, since the kit keeps that caliper. The best compound depends on how you use the car, so we leave that choice to you.

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.

    Fits ok.

    Fit perfectly on my S13, with just a little bit of trimming of the knuckle and caliper. Used a set of Infiniti Q60/Q70 rear calipers, exactly the same as 370Z and more readily available. Any of the Akebono calipers with 4101 casting number should work.

    Bought this conversion kit for my RWD Stagea running 32GTR sumitomo callipers, everything fit perfectly and as it should, very happy with the quality of the items received.

    I recently upgraded my Nissan S15 with these brake rotors and caliper adapters, and I am thoroughly impressed with their products and service. The materials used are high-quality, and the fitment and precision of their product was perfect! Originally I just wanted to enhance the aesthetics of the car with bigger brake rotors! But after the install of their front and rear rotor upgrade kits along with fresh brake pads, I noticed a significant improvement in braking power moving from old worn disks to theirs, not to mention better an overall driving experience. The installation instructions provided were clear and easy to follow. Even if you're not a seasoned mechanic like me, you should be able to install these with minimal hassle using their installation video’s! They are great value for money, I highly recommend HFM part’s to anyone looking to upgrade their braking system for better looks and performance!

    This master cylinder did exactly what they said. Direct bolt on. And just works. We tested it in our Endurance v35 and had performed spot on. If your looking for an upgrade for your 25mm master I highly recommend this for a firmer pedal feel.

    We are currently running the 2 piece brake discs on our endurance race car and they are doing a great job. The weight saving, cooling, reduced replacement cost and the look are all great points as to us returning for more. The team at HFM are knowledgeable on there product and are commited to working through the intricacies of racing with us. GREAT JOB!!
