Will this work?
 

I have stock 17x8 bullitts up front and 17x10.5 bullitts out back. With my Car being lowerd, 17X8s look a little werid with the huge tire in the back. They are too tucked in, and I would like them even with the fender. I was thinking about purchasing maxim motorsports 1/4" spacer, but I've never really heard of anyone putting spacers up front. Would this work??

Yes it should work, but i don't know if the wheel studs needs to be replaced for longer ones.

Post up some pics, so we can judge if we think you need spacers or not. (sig looks good)

17x 10.5s out back-what size tire are u using? - I want to put wide meats out back on my 06 Stang but not sure whether to go with 17s or 18s.

Thanks :)

running 275-40 X 17 and they look nice!!! a little over 10"s wide maybe a little more, its about as wide as you can go on the stock '06 rims, don't remember if they are 8" wide or 8.5"

too late. I just ordered some some 17 x 9 rims with 275's. Decided I'd rather not mess with the spacers and just buy the actual thing.

That was going to be my suggestion if you had the money for it. Good call.
