I am looking to install spacers for my wilwood big brake kit to clear my stock AE 17" rims.
Anyone have ideas of what I should be looking for?
15mm?
Also I have been looking at some applications and I am wondering if the H&R wheel spacers are the way to go?
With the H&R kit installed what is wheel gap from outside of tire and fender? how far can I go? If I am slammed (or decide to slam the car) how far out can I go?

Feedback is helpful thanks.

 

I'd first check that it is be okay to push the wheels/tires out that far. Your concern really isn't how it looks and the gap to the fenders, but if you're going to get any interference once the suspension actually has to move. 15mm is quite a bit of adjustment and you might find your previously well-fitting wheels/tires suddenly rubbing fenders, fender liners, etc.

I'm also wondering if this will give you a lot more steering kickback...

I'd post this in the 5th Gen forum if I were you, because what fits and what hits with regards to wheels/tires and BBKs is so specific.
