340mm Rear Brake Upgrade Kit

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!

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.

Fitted these on my 22 brz.. very happy with the results. I cooked my projuct mu pads in 2 session at luddenham. With these I was running consistent laps with absolutely no brake fade. And extremely fast shipping

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!

Easy install works perfectly on my track car

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.

Awesome upgrade and still retaining stock calipers. Combined with the rear brake upgrade and HFM BM57 master cylinder. Great long lasting stopping power we have street and track tested this combo with great results. Its totally transformed the car. Great after sales service cheap as and fast shipping. Thanks to HFM Dot Parts for the killa and ultra simple upgrades keep up the great work from the team at Noakie Spec Racing https://www.facebook.com/NoakieSpecRacing

Very simple to install would highly recommend these parts for your silvia

Great quality and fitment, super fast postage. Very happy

Super stoked with this rotor kit, easy install and braking performance is noticeably better. Plus they look awesome!

Installed these on my s15 and couldn’t be happier, huge upgrade from the standard rotors, they look great and perform even better. Install was pretty straight forward Would definitely recommend

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.

Every thing fitted perfectly looks cool amazed how they can make for price I paid

very good and great repsonse times, product feels good

Very good would go through them again

yeah great install havent used them yet but sure they will be great

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.

Hfm.parts has done it again with their excellent customer service! And quality of product. Thank you

N/S, still haven't looked at it yet.

Overall an easy install, everything works great and looks fantastic!

Excellent service, fast freight time, will most definitely use again.

Very good upgrade choise.

Good soize, 2 seconds stop. Not bhed
