Our compatibility list is based on OEM specifications. Variations may exist due to vehicle sub-models or other factors — verify fitment before purchasing.

We have only confirmed fitment for the vehicles mentioned under compatibility. If your vehicle is not listed, then we don't know if it fits.
Yes, you are required to linish/polish the caliper or knuckle side to avoid binding. Please refer to the installation video/guide for assistance.
There will be ~1-2mm of pad overhang; please refer to the reference photo above. This is because the adaptor works by spacing out your existing calipers, which in turn, the brake pads position will follow, to accommodate 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.
When installed properly, this adaptor bracket sits close to the lower control arm. In general, if your car retains the OEM stopping position, there should be no interference while using this adaptor. However, we cannot confirm its fitment with any aftermarket products that can change your steering angle.
While you can retain your OEM brake lines, they will likely be at full extension. We recommend replacing your OEM brake lines with longer braided brake lines.

 

 

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.

Modifying vehicles is a specialist task and requires the knowledge and experience of competent individuals to be conducted safely.
We recommend this product be installed by a competent person. Instructions are given with every order where available, however, If you would like a copy prior to ordering, you're welcome to contact us
