Separate issue now. Our track being run dry and blue grooved. My car is traction rolling everywhere. I can't push it at all... unless it's going straight.
I stiffened the shock oil incrementally up to the thickest oil the hobby shop had, 60wt Losi. ...and the smallest hole pistons I had (1.3x8 down to 1.2x8), cut some droop, lowered the car and went to a stiffer front sway bar (2.3mm to 2.5mm) and heavier springs. With these changes the car was massively better, but it's still not enough.
I'm not sure if raising or lowering roll center would help more or if longer links would help. I'm trying to apply the statement of how a 'low roll center is the most chassis roll (least wheel lift potential)' to my new issue, or if it does. Would more chassis roll make the car more likely to roll over? And also start lifting wheels off the ground since the chassis is rolling over?
