Ya unfortunately it did not help me. I have done that as well as completely disassemble the rear pod and car at one point. It is almost as if a hole somewhere on the chassis is drilled slightly off. The chassis on a flat piece of granite was pretty much perfect with maybe a very slight .1mm lift in the front. I can get the car even side to side using the side spring preload but then the car has a 60gram side to side difference on the front tires which obviously makes it drive completely different right to left.
