Centering Rings Explained

We've explained the benefits of our interchangeable centering ring system in detail. We've told you how they work and even how we make them. It's time we show you how they work!

Easier said than done... Once installed, our centering rings are literally buried under the wheel. Removing the centercap reveals a bit of detail, but nothing worth sharing. We needed a cross-section, so we set out to do exactly that. The ingredients for this recipe included an OEM 5x112 wheel, an Audi TT, and a 15mm 5x100-5x112 wheel adaptor. We used a 57.1mm centering ring to fit the OEM wheel.

First we marked the wheel in a few strategic locations and ran it through our vertical bandsaw. Next we test fit the adaptor in the wheel and marked a few cuts that would best display the mounting hardware. The adaptor was sliced in half, along with a centering ring and the OEM center cap. Mounted to the hub, the assembled wheel and adaptor clearly display the inner workings of our wheel adaptor and interchangeable centering ring system. Check out the photos!

At first glance the cross section seems a bit messy. We made sure to include every detail, even at the risk of over-complicating the photos. The centering ring itself is one of these details, clearly visible in every aspect. Take a look at the precise fitment of the centering ring around the hub. The fitment of the centering ring inside the adaptor is just as tight - proven by the compression of the o-rings. The centering ring clears the hub internally as it protrudes past the adaptor and into the wheel. This particular wheel has one of the deepest chamfers we've ever seen, but was still reached by the centering ring.

These photos also display the big picture. The whole point of our centering rings in any size is to achieve wheelcentric fitment. Hubcentric fitment is provided by the adaptor body. The union of adaptor body and centering ring results in true wheel & hubcentric adaptor fitment. The wheel is aligned with the centering ring, the centering ring is aligned with the adaptor, and the adaptor is aligned with the hub. Concentricity is effortlessly achieved.

During a photoshoot for our installation instructions we also managed to get some photos of our centering rings in action. Starting from the left, the first photo shows the empty adaptor bolted to the hub. The next photo shows us putting a drop of oil on the o-rings to lubricate them. The centering ring in our hand gives you a good idea of the actual size. Next we pressed the ring into the adaptor. The fitment is tight, but very little force is needed to install the centering ring. Next we removed that centering ring and installed one of a different size. The first centering ring installed was 57.1mm and the second was 66.56mm. The last photo shows the wheel installed and the center cap removed. The centering ring is clearly visible.
