XP12 front and XP8 rear with no complaints. I'll stiffen the shocks and give it a tryout. My car is slightly loose with light throttle in the eses. I can really feel the front tire grab the pavement on turn in. So far no understeer. ***** at the wheel syndrome perhaps? Oversteer on exit if not careful. I switched to a 3:27 rear gear recently. Now I exit the long sweeping corner in 3rd instead of the top of 2nd. Under the bridge I used to downshift to 2nd and now the car stays in 3rd. Time will tell if the change was worth it.
