On the rear of the CRC cars, we shim up the pod plates (how much varies if you have a slider rear pod or not) or you can use our F1 pod plates. I know shimming up the pod plates seems "wrong", but you can not tell the difference on the track.
On the front, we add shims between the front plate and the chassis and just use longer screws.
Other than having your car in front of me (which is always a possibility), or you posting pics, all I can tell you is what we do.
We want WGT-R to grow, so if that means working on other brands, we are more than willing to do it.
