What size tires are you guys running on your cars? If you're running foams, they may be too tall. Even with the correct ride height you need to cut your tires down. You can't run foams out of the box with decent traction or they will traction roll. At a club race I start mine around 2.3 to 2.28". New, there is too much sidewall causing way too much side bite causing the roll. R.W.
