324mm Rotor Caliper Adapter Brackets

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.

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.

Worked great but should supply another set of washers, ran into slight clearance issues. Had to stack the older ones to provide just enough clearance

Easy install works perfectly on my track car

Great quality, super light and actual bolt on fitment. Great budget upgrade for a street 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.

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 quick shipping during pandemic. Allowed me to install straight away

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!

A true bolt on product. It is a perfect fit and super simple to install. The finish and overall quality of the product is 10/10.

Everything bolted up just how the instructions guided. Great fitment and easy to install. The only downside is I couldn't justify ordering the whole kit with rotors due to the shipping being high. This should be marketed more in the US since no one is doing it here. 10/10 would recommend to anyone looking into a rotor upgrade on their car. Top marks for this company!

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.
