I've only traction rolled because one corner exit/entry into another at my track puts the truck facing sideways down a steep slope in order to punch it onto the main straight. Only rolled if I tapped the brakes. But it could also be my roll centers as I've changed them from kit setup.
I've changed the front springs, roll centers, rear shock angle, front toe out from the kits. The kit setup seems to be more setup for the US point and shoot style of the US tracks.
