What do I need to know to choose slicks for my race car?

Swap out to beadlocks or have your current rims converted. You won’t have to worry about spinning the tire on the rim with whatever tire you choose. Beadlocks can also allow you to play a bit with the tire size and sidewall stiffness. My car is very similar to yours and getting my rears converted to a double beadlocks made a huge difference
