Overview

Why upgrade

This rotor takes the rear from the factory 297mm to 337mm. It runs your factory caliper and pads, spaced out with our 337mm caliper adapters.

This is our V2 design. The external vent design is adapted from our 340mm rotors, and the pad sits fully on the rotor face with no overhang. The slots match our 324mm front rotors, so the front and rear look like a set.

Ready to fit

Every rotor is runout tested and balanced before it leaves us, so it’s a direct bolt-on straight out of the box.

Will it fit my car?

Suits the Nissan Skyline R32 GTR, R32 GTS-T, R33 GTS-T and R34 GTT with factory non-Brembo rear calipers. You need our 337mm caliper adapters and 17″ wheels or larger. Want the lot in one order? The 337mm rear brake upgrade kit includes these rotors and the adapters. Brembo rear calipers? See our 340mm rear brake upgrade kit for GTR Brembo calipers.

Fitting

Remove the caliper and rotor. You may need to peel back or remove the outer edge of the backing plate. Fit the adapter to the inside of the knuckle, onto the stub axle, using the cap head bolts and a thread sealant such as Loctite 262. Then fit the new rotor and refit the caliper to the adapter with the hex head bolts. Step-by-step photos are in the 337mm rotor caliper adaptor install guide.

We recommend installation by a licensed mechanic.

Our compatibility list is based on OEM specifications. Variations may exist due to vehicle sub-models or other factors — verify fitment before purchasing.

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.
Yes. They need our 337mm caliper adapters to space the factory caliper out. The 337mm rear brake upgrade kit includes both.
You need 17" wheels or larger. Wheel sizes vary across these models, so check yours before ordering.
Yes. Your factory caliper and brake pads both work with this rotor.
These are designed around the factory non-Brembo caliper. We can't confirm fitment with other calipers. Brembo rear calipers? See our 340mm rear brake upgrade kit for GTR Brembo calipers.
No. You can fit them on either side of the car.
That's where the rotor was balanced. Material is machined from the outer edge until it's in balance, then runout is checked before it's packed.
The V2 uses an external vent design adapted from our 340mm rotors and gives full pad contact across the rotor face.
To our knowledge, our 337mm rotors are unique to HFM.Parts. We'll keep making them as long as there's demand.

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.

    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!

    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!!

    Using the 2 piece rotors on our endurance car and so far the results are good. Huge weight difference, better cooling, cheaper rotor replacement,and the look is just a bonus. The HFM Team are great with there backup service and comitment to working on some of the more intricacies of a race car. GREAT JOB.

    Bought these rotors as a replacement for my OEM ones which were warped when I bought the car. After a slight mix-up with a separate distributor (which Dom was more than happy to rectify, no questions asked), I fitted them yesterday. Installation was easy and they fit perfectly. They're noticeable lighter than stock, so much so that I can feel it in the steering of the car. They have very tight tolerances between the caliper and the rotor, and the materials feel beautiful. Clearly an extraordinarily well-made rotor. Bedded in some new pads and the rotors last night and they feel amazing. Look the part too, which is always a plus! Can't wait to try them out in khanacross events and track days later this year, but from the looks of them they'll more than hold up! Can't wait to check out the rear rotors you guys make when they come out! Thanks!

    Very nicely made up kit, my only issue was being 2 flat washers short in the sealed bag "no biggy had some spares in my garage" and the pre assembled 2 piece rotors bots not being anywhere close to the recommended torque specs of 13-15 ft lbs so make sure you checked them! Paired this kit with a new set of Project Mu HC800s and have only had time to do the bed in process so far. But everything feels great. Can't wait to see how they go at my next time attack day.

    Purchased this brake set because of their price point. Turns out they’re an amazing set of brakes, improved over stock stopping power by miles. 2 piece rotors are also a nice treat for the calipers. The Wilwood calipers looks great and reduced much weight vs stock. Would recommend.

    Ive been tracking my car for almost 2 years, this kit has seen about 20 track days. Easy to install and even easier to maintain. Before the HFM rotors I was using DBAs that used to warp every 3-4 track days. The two piece rotors have lasted 8 track days so far and have so much more in them. If anyone is thinking about this product, trust me get it. Completely changes the vehicles braking ability, and still to this day never had any brake fade. HFM keep the good quality throughout all their products and looking forward to purchasing more products from them!

    These rotors had no brake fade with over 500km's of back to back driving during a Grip Day (circuit). Brakes never got a chance to cool down and at the end of the day there was no lip on the rotor. These rotors were fit to a Nissan 370Z with Forza FP3 Brake Pads and Hankook RS4 tyres.

    Compared to the front upgrade, this is an absolute breeze and the front isn't even that much of an issue. I found myself cleaning up the hub and surrounding areas more than I did installing the adaptor - a testament to the ease of the install. Super straightforward install, as simple as the video makes it out to be. Love the look of the slotted design and the size really fills out my wheel. From what I can discern, it has similar braking properties to factory, but the real difference will be under constant braking. Great piece of gear, great work HFM!

    Opting to keep my 17" wheels, this upgrade was the perfect choice. For a car that endures regular light track work and spirited driving this kit is ideal. The stock brakes are more than capable of pulling up my - and arguably most - 32 GTR, however they suffer and fade from consistent use. These rotors now provide less brake fade due to the larger 2-piece rotor dissipating heat more efficiently and effectively. The unboxing was great, all the parts came clearly separated allowing for an easy install and the rotors came assembled which was superb. The install felt tedious, though this was due to me constantly test-fitting the adaptor as I shaved the knuckle - trying to shave as little as possible. The install video was an excellent guide and helpful with torque settings too! This was a no brainer for my application. The rotors are about 1kg lighter than the stock 296mm equivalent which is 1 less kilogram of unsprung weight either side which is a great improvement. They are also very aesthetically pleasing. Greater braking endurance, reduction in unsprung weight, extremely cost effective compared to going a true BBK. This is an excellent upgrade for anyone wanting to retain the stock caliper but wants to enhance performance. After considering the other options (Evo Brembos, R33/34 and even R35 GTR Brembos and Endless/Project Mu), this came out on top. Great piece of gear HFM, keep up the great work! These brakes fit under R33 GTR Wheels, 17x9 +22 Advan SA3R's and 17x9 +22 Sparco Crimson.

    I did have to grind off a little caliper metal on drivers side only, the cap head bolt interfered with it, not a big deal, I guess there is variance in the stock nissan caliper forgings, once assembled its all been rock solid for the 2 weeks of daily flogging I mean driving the car gets.

    Hi there, Apologies for the delayed feedback. This weekend just gone was the first opportunity to install and use the rotors. So far I am very impressed with these.. the previous cross drilled rotors would either crack on the first race day or crack on the second and the new non cross drilled items have survived a 2 day race meet so far with in excess of 50 laps of Barbagallo raceway on them... Which equates to approx 120km of racing of which we finished in second place and set our pb lap times. Thanks again. I would def recommend them as an upgrade over the older cross drilled style. Thank you again. Regards Andrew Souvertjis Facebook page: 265 Motorsport
