Setting mine up for the first time this Friday. I have a lot of work to do before then and kinda dont want to even run yet. I accidentally bought radial tires and realized I should change my rear pinion and motor shims. I had to buy a new body and swap the bearings over to the new wheel set tonight. My SC430 rear tires keep rubbing in sharp turns on the larger track.

Do I really need to shave down my tires?
Should I run the radials I accidentally bought?
Radial vs Slicks on RCP?
