would i rub or should i go with the 7 in on the front, the wheels i want only come in 7's and 8's

 

What wheels and what are the offsets?

 

Offset please. Offset is what makes and breaks the wheel

 

are 17x9, 63 offsts, 235/40 tires gonna rub in the front????

 

no, they wont rub... but what size are you using in the rear?

 

17x9 all 4 corners 255/40 tires for the rear

 

do you plan on running 235 on all four?

i don't think it's a good idea to have a stretched tire up front and a square sidewall in the rear, it'll change the characteristics of the tire.

run 245/40/17 on all four if you want...

 

235/40 for the front and 255/40 for the rear is what the guy at tirerack suggested....i already orderd them =/ 245/40 wont rub in the front?

 

So the rims your getting aren't staggered?? I dont really think its a good idea to not have staggered wheels on your s2k. There is only one s2k that i've seen without staggered wheels, and thats because he had rota's ( at that time rota didnt offer staggered wheels for the s2k, they now offer a few in staggered sizes). So if your rocking 9' all the way around , your just staggering the tires.

 

no 17x9 at all corners...just diffrent tire sizes
