At HFM Dot Parts we have made a very simple big brake upgrade kit which allows your existing rotor size to increase from 292mm to a noticeable 337mm. The way we achieve this is by using our own custom designed and developed adapter set, this enables you to use your OEM caliper; making this a very affordable big brake upgrade kit. The Midnight Edition black painted hub adds to the rust resistance and prevents your rotors from looking dull and are slotted to suit our front rotor options for a uniformed appearance.
1x Pair 337mm Rear Rotors

High Tensile Nuts & Bolts for Fitment
Q.If you stop making these rotors, is there anywhere else I can get them from?
A. To our knowledge, our 337mm rotors are unique to HFM. We will continue to produce these rotors and any other products as long as there is a demand.
Q. Will these fit my OEM R32, R33, R34 wheels?
A. These models can have different wheel diameters, we encourage you to double check your wheel size before purchasing. You must have a minimum of 17″ wheels!
Q.Will my original brake pads fit this sized rotor?
A. Yes, both OEM Caliper & Brake Pads are compatible with this rotor.
Q. I have an aftermarket caliper, can I still use this rotor kit?
A. No, this brake kit has been designed to suit your OEM caliper. We cannot confirm if it will also suit other calipers.
Q. Why can’t I purchase the adapters without the rotors?
A. To the best of our knowledge, the 337mm rotors are unique to HFM. Because of this, purchasing the adapters solely would be useless without the rotors. If you would like to purchase the adapters separately, you can contact us to purchase a pair.
Q. What material are the adapters made from?
A. Our adapters are made using high quality T6-6061 Aluminium.
Q. Are these rotors directional?
A. No. These rotors have pillar veins so can be used interchangeably.
Q. Do I have to modify any brake components to use this kit?
A. Yes, you will need to modify the knuckle in order to fit the adapters. Please refer to our install guide above.
We’ve created adapters that have been finely crafted to suit the popular American-Trusted Wilwood Caliper and Australian made DBA Rotors. Our adapters enable you to increase your rotor size significantly from 277mm to 326mm to optimise your braking power and better heat disbursement.
