and if they do what tire size would i need?

and would i need spacers?? and what size spacers


thanks
These will fit with no spacers needed. I'm running 275's or 285's in the rear. If your car is lowered you may get some rubbing on the inside of the fender wheel out back, you should have no issues in the front.

I run an 18x10 ET40 rear, its a touch too far out (no clearance issues, but I'd like it to be about 5mm further inboard). Stock ride height you should have no problem. I run a 265/35-18

i have a set. your goal is to have tires that are just over 25" in diameter. you can check the tire rack's spec lists like this one to get the sizes:

http://www.tirerack.com/tires/Spec.jsp?make=BFGoodrich&model=g-Force+T%2FA+KDW+2&tirePageLocQty=

a 265/35 will actually be a better fit for the car. the 275/35 is a tad tall. i'd go with a 265/35 or a 285/30. what size are your fronts?

i chuckled when i read this because you are talking 3.5 mm or roughly 1/8 of an inch. That's tire wear after one DE or weekend ride through the twisties. If you can eyeball the difference, you are really good. i didn't calculate the effect on gearing, but it can't be much
