Overview

Why upgrade

These brackets let you fit factory 370Z front Akebono calipers and 354mm rotors to the R34 GTT, up from the factory 310mm rotors. They’re machined from T6-6061 billet aluminium, hard anodised, and fitted with stainless steel Heli-Coils so the threads hold up over time.

Will it fit my car?

Built for the Nissan Skyline R34 GTT. You’ll also need:

HFM.Parts 354mm front two-piece rotors (Z3544932) or an OEM 370Z equivalent
A pair of 370Z Z34 front Akebono calipers
18″ wheels or larger

The factory brake lines sit at full extension with these brackets, so we recommend our front hard line delete braided brake lines. Want everything in one go? Grab the 354mm front brake kit for R34 GTT.

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.

Fitted correctly, the bracket sits close to the lower control arm. If your car keeps the factory steering lock, there should be no interference. We can't confirm fitment with aftermarket parts that change your steering angle.

You can keep the factory lines, but they will sit at full extension. We recommend our longer front hard line delete braided brake lines.

Our 354mm front two-piece rotors (Z3544932) or an OEM 370Z equivalent.

No. You supply a pair of factory 370Z Z34 front Akebono calipers.

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.

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.

HFM.Parts 300mm Rear Brake Upgrade Kit for Nissan Silvia S13, 180SX, Silvia / 200SX S14 & S15 (Rotors & Caliper Adapters) →

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 team at HFM are knowledgeable on there product and are commited to working through the intricacies of racing with us. GREAT JOB!!
