I have a Cobra Rs on my 89 Gt. 9" 245/45 up front and 10.5" 275/40 back
Could I put street slicks of any type on my car without modifying car ? The quad shocks aren't a big problem for now, but I could ditch them for u/l control arms
i have hoosier 26x9.5 on turbines, i also have cobra r 17x9 wheels, and the slicks are and inch taller and actually skinnier, i dont know if you are going to be able to get 17" slicks
good luck!
