First thing I would check is to see if your foam tires are perfectly true.
I would turn on the car and blip the throttle to see if your foam is out-of-round.

I encountered a similar situation where the left side of the rear pod (under the axle) was 0.4 mm lower then the right. I discovered the set of newly trued foams I bolted on my car were not perfectly placed on the arbor. *I wasn't using my tire truer at the time. The arbor wasn't set correctly in the wheel, after a few cuts here and there I couldn't tell if it was out of true. However, after cutting down and mounting to the car is when I noticed the tire was out-of-round. The ride height even'd up after putting on a new set of properly trued tires.



I'm not saying this arbor is bad, it's probably one of the best out there. Please make sure 100% you know how to operate the truer and understand how the arbor functions. For me, this is the one I had difficulties with and caused the tire to cut out-of-round.

KNOW WHAT YOU ARE DOING!
