are the stock 16x7.5 wide rims the smallest that will fit??

 

why do you want smaller? Are you looking at putting some Dayton wire wheels on your S2K?

 

i think with 15s you will touch the brake rotor?
and like Seattle2k said, why would you want to go smaller?

 

why?

 

I seriously doubt it, and you definitely won't get them on the front due to clearance issues. It would have to be a VERY open 15" wheel.

*edit
I wasn't thinking like a proper tire and wheel whore, those will fit fine, all you have to do is remove your brake calipers, cut a hole in the floor, and stop the car like Fred Flintstone. Yabba-dabba-doo!

 

I am guessing for drag racing.

For a funny picture I put my weld draglites on the back of my s2k (off my camaro) and they were close but didnt rub, Welds have alot of room inside. Mine are 15x8. But honestly if are trying to get rims for slick they make alot of slicks in 16's. and then as long as you dont wanna run super wide tires you can use ap1 rears.

 

yes I want them for slicks, smaller the rim the better.

So I take it nobody has fit 15s on the rear?

I contacted tirerack and the guy told me with the info from there data that if isn't possible but he wasnt sure if it was impossible

 

a 15x8 would be a little better than the stock 16x7.5 rears. I plan on running the mickey thompson ET street legal slicks with a size 26x10.5x16 on the stock rears if I can't find a 15in rim to fit

 

there has got to be somebody out there that has tried to run a 15in rim to hook up better with slicks....
