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.

    Installed this on my 22 brz. Have a chassis mounted shifter and this has made it much more smoother definitely recommend if installing a aftermarket shifter.

    It's a pivot ball, seems to be very well made, and feels heavier than the OEM one. The OEM one looks like the tip is slightly more round and circular than this one but it might be because it was worn out. Functionally it feels the same.

    After installing these I could feel near to no bump steer. The bushing quality is much better as the OEM bushes as they seemed to be worned pretty bad from wear and tear. Especially on lowered cars this is a must to get the steering feeling how it should been from factory. Highly recommend these to eliminate and bump steer caused from the suspension. Cant recommend HFM enough, been using their parts from day dot on this car, every part is top quality.

    This little unit completely removed my clunk on gear changes under hard acceleration. It does transmit a small amount of gearbox noise but it's minimal and thats coming from someone that drives around with the exhaust silencers in :)
