I got a set of Racing sparco 17x8.5 of real cheap and was wondering if they would fid my my car since they are all 8.5" wide. also I just bought new tires fo the stock rims about 1.5 months ago and was wondering if they would fit on the 8.5" wide tires.

 

That would depend on the offset of the wheel.

 

Racing Sparco NT-R Wheels 17x8 30mm

 

The OEM rear wheel is 17x8 +33mm. Your wheel will be 3mm closer to the fender. No problem.

For the front wheel just use a offset calculator and compare your wheel to the OEM wheel.

 

all 4 wheels are 17X8.5
