Overview

What they do

Aftermarket wheels often have a centre bore larger than the hub they sit on. A hub ring fills that gap so the wheel sits 100% centred on the hub. That helps eliminate vibration, loose wheel nuts and extra stress on the wheel studs.

Will they fit?

Two measurements decide it.

Car hub bore = ring ID. Your hub must measure 66.6mm.
Wheel bore = ring OD. Your wheel’s centre bore must measure 73.1mm.

Suits: Mercedes-Benz models with a 66.6mm hub.

Car not listed? Measure the hub. If it’s 66.6mm, these rings suit.

Product Information

Fitment for this part hasn't been listed yet. Ask us and we'll check it against your car.

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.

Match two measurements. The ring ID must equal your car's hub bore, which is 66.6mm for this ring. The ring OD must equal your wheel's centre bore. For example, a 66.6mm hub with a 73.1mm wheel bore takes the 66.6mm ID to 73.1mm OD ring.

They suit the Mercedes-Benz 66.6mm hub. For any other car, measure the hub. If it's 66.6mm, these rings suit.

One pair covers two wheels. Order two pairs to do all four.

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.

These are literally the best hub rings Ive had on any of my cars. I know I have a soft spot for machined parts but it's such a snug fit. Accidentally ordered an extra 2 pairs but honestly don't care that I paid double what I needed to, they're just what I needed and now I have spares I guess haha.

The quality of the product looks and feels excellent. Had a nice firm fit on my RPF 1s. As well as on the hubs of my WRX. Will definitely buy again. I would also like to thank HFM for the fantastic customer service in dealing with shipping. After contacting them regarding shipping issues, their response time was only minutes after and then offered to send me another set of rings as the original courier lost them.

I needed these to fit Rays Volk Racing RE30 wheels to a Toyota 86 but they were surprisingly hard to find in Sydney these fit perfectly and have stood up to several track days with no problems
