The best way to understand which size spacer you need, is to simply measure from the top outside edge of your tire to the inner lip of you fender. This will give you the best idea on how much size you have to work with, and to decide on how much your wheels need spaced.

Once you know that let we will be able to recommend which size will be the best fit for your application.

Here is a diagram that might also be of some help...

if you want legit fitment, buy 3 different sizes. 5, 10 and 15mm trial and error. 9 times out of 10 you'll put on one size because you are not "sure" then end up buying another set to push them out farther. i started with 12/10 on my OEM 19s now i am at 20/15

OK, I'm a bit confused. I measured my gaps over the weekend using a metal bar laid across the face of the tire (Potenzas on OEM 19s). Measuring the front, I got 1/2" so 12-15mm should be right. However, in the back, the bar hit the middle of the fender lip (bar is 1/8" thick) so I'm thinking I shouldn't even do spacers. Not sure how anyone could get by with 10mm spacers in the back based on what I am seeing without some camber dialed in.
