I see most have posted using the standard purple / gray Jaco combo for stock. I actually had problems with this combo the past few times out. I felt the purple fronts would get too gummy around 6-minutes and the car would oversteer and lap times drop signitficantly.
I switched to black / yellow Jaco combo and found this tire selection much better suited. The laps times were consistent the entire 8-minutes. Anyone have any thoughts on this?
I'm too lazy to try and run the Parma tires...as I'd have to re-shim the rear axle.
