Thanks for all this information guys!
I just got back from getting the 20's put back on. And to my surprise, these tires are actually
BETTER than the stock 18s. I don't know if it's from the hub rings, Stillen sway bars, or from changing the tire psi to 45 (max is 50). But overall I am very happy compared to how the car felt a few months ago with these wheels. I actually like the way they feel and sound which is quieter than stock..I can hear the exhaust more
But it definitly needs 20-25mm spacers for the rears and some coilovers and I'm set! I'm shocked I didn't even need a balance or alignment
