I've heard wheel size affects an alignment (as it affects your ride height), but that you don't want to get an alignment with nice wheels as they may scratch them. Should I keep my original wheels on for my alignment or put the new ones on for a more correct alignment (the new wheel/tire assembly will be .4 inches taller than the original stuff)?

 

hey I'm interested in that too since I just put on my 15" K1's 195/50 Kuhmo's. How important is an alignment? Scratches =

 

Tell the shop or whoever is doing your alignment to watch out for the curbs. I did mine myself on an alignment machine w/o any scratches. So they need to be carfull not to be sloopy and careless. And of course do the alignment with the wheels you are going to using.
