Upgrade your braking performance with the HFM.Parts 300mm Rear Rotor Kit, designed to deliver a big brake feel without the big price tag. This kit increases the rotor size by a significant 42mm over the OEM standard, giving you enhanced stopping power and a bold, performance-inspired look.
The kit includes our Australian-designed and developed caliper adapter set, allowing you to retain your OEM caliper for a seamless, cost-effective upgrade. The precision-engineered adapters ensure perfect fitment, making this a practical and affordable big brake solution for your build.
The rotors feature a striking slotted design that matches HFM.Parts 324mm front rotors, providing not only a cohesive appearance but also improved braking functionality. The curved indentations enhance pad cleaning and ventilation, while the black painted hub resists rust, keeping your setup looking sharp and performing reliably.

- Custom Caliper Adapters: Use your OEM calipers with our precision-designed adapter set for an affordable big brake upgrade.

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.
