Tentative plans are to run a 305 on a 10.5" in the next month or so.

 

I started with conventional wisdon of sticking with a stagger but just closing the gap. 285 front and 315 rear. I havent felt understeer yet but I think I may have not been agressive enough with wheel size. I'm running 18x9.5 front and 18x10.5 rear. Thinking I need to go to 10 front and 11 rear. Or maybe go square? Not sure of offsets required yet.
