alignment question 18 and 19's
I have 2 set's of wheels for the rear. One pair of 18x10.5s with 305/35/18 Toyo Ra'1s and a pair of 19x11 with Micheln sport cup 305/30/19's.
When I do my alignment should I have the 18's or 19's on there. There is a 1/5 difference in height. I plan to do some road racing soon. What do you guys think.
My fronts are 275/35/18 Ra1s if that matters.

What do you plan to race on? I'd do the alignment on those and sacrifice something on the street side... if you plan to race on both you'll just have to pick the ones you think you'll run the most or what you'll run when "serious" I guess.

It's a tough choice. The 18's Ra1's I have are kinda worn and the 19 cups are almost new.

FWIW, 1/5" = 0.2in. 4/32" = 0.125in. Meaning if you start with 4/32nds tread and run to the cords you're already seeing half of the change in diameter. So a worn MPSC will be roughly the same diameter as a new RA1... call it a wash in the end?
