PS Cup 2's: Run Flat vs Non-RF
Anyone have experience having used both? Soon will need to re-shoe for the track. Added Conti's for the street and kept the Cup 2's for the track but coming time to decide. The RF's have done pretty well on the performance side, stiff sidewalls have meant minimal roll and shoulder wear, so am wondering if I should change.

Massive difference. Completely different tires. If you want track grip, keep going with the runflats.

The factory shocks, leaf springs, sway bars and steering were all tuned for the stiff sidewall runflats. I imagine going to non-ZP would result in a car that may have the same levels of grip, but at the cost of steering response and lateral control.
