HFM.Parts 300mm Rear Rotors are designed in Australia featuring a striking slot design that matches all of their 324mm front rotors. This solid rotor has an increase of 42mm from the standard sized OEM rotor.
This is achieved by using HFM.Parts Australian designed and developed custom caliper adapter set which enables you to use your OEM caliper. Making this a very affordable big brake upgrade kit.
The indentations on the rotor surface have a slight curvature to improve cleaning ability and ventilation, paired with a black painted hub to improve rust resistance and complete the overall look and performance of the rotor.

Q. If you stop making these rotors, is there anywhere else I can get them from? A. To our knowledge, HFM.Parts 300mm Rotors are unique to HFM.Parts. We will continue to produce these rotors and any other products as long as there is a demand. Q. Will these fit my OEM S13, S14, S15 wheels? A. No, your OEM S13/14/15 wheels are 15″. The minimum wheel requirement is 16″. 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. If I break/damage/misplace the adapter, can I get a replacement? A. Yes! You can purchase our adapters on their own under the adapters category. Q. What material are the adapters made from? A. Our adapters are made using high quality T6-6061 Billet Aluminium. Q. Do I have to modify any brake components to use this kit? A. Yes, you will need to cut and straighten the backing plate/dust cover. Q. Why doesn’t the brake pad cover the entire surface of the rotor? A. This kit works by spacing out your existing calipers, which in turn, the brake pads position will follow, to accommodate for the larger rotor. There are no brake pads (that we’re aware of) that will fit within the original caliper and cover more surface area. Q. Are these rotors directional? A. No, you can install them on either side of your car without affecting performance.

    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.
