Thank you Edward for looking into this.
The rearpod is tweak free, sidelinks are free, diff is rebuild and smooth and the bearings are brand new ceramics. We use a setup station. The only thing I noticed, after watching your YouTube channel, is a slide toe in when the front is compressed. Cloud it be the cause of this?
As for the tires, I know that other people run the same compound with no issues at all. I even run the the same tires on my mod without this problem.
