- Alexander Hagberg - Tech Tips - Static Camber Angle Changes -

Some people have asked me why the static camber angle sometimes changes after a run, even though you didn't hit anything? This is an interesting question, which I have been trying to figure out myself. Thanks to some input from other team drivers, we have found a trick that will limit this change to a minimum.

The black wheel hub (also referred to as the hex), which the wheel mounts onto, has a tiny screw that tightens it to the wheel axle. There is only a very thin bit of aluminium material between the screw and the outside. As a result, when you tighten the small hex screw, the aluminium might warp slightly outwards, which in turn can affect the static camber on the wheel. As you can see in many of my setup sheets, I am often using the optional narrow hexes, -0.75mm (part no. 305351). This hex, due to being narrower, has even less aluminium material in that spot just mentioned, which makes it more prone to this warping as well.

There is a quick and easy way to overcome this though. Before you tighten the small screw in the hex, use a wheel nut or Hudy setup wheel nut (part no. 109360) to tighten the hex against the pin, before you tighten the small screw. This way the aluminium won't warp, and thus, it won't affect the camber anymore.

I always set my camber in the Hudy setup station (part no. 109305). Make sure that your car is race ready and has a battery in it, to have an accurate measurement.
