Default 18 inch wheels on all four corners

First, I would like to find out if 18s will fit on the back of a base model.
Second, I would like to know if I can run 18x9.5 up front.

I'd like to run 275s up front and 295s out back on 18x9.5 and 18x10.5 TSW Interlagos.

Anybody know? Any other suggestions to achieve this maybe with different wheels? Looking to stay in the 18-21lb range for wheels and 500 or less per wheel.

Yes they will. Did you not ask this same question a few weeks ago?

Default im in the same boat as you!

i have( 8 )2002 aftermarket zo6 wheels and now a c7 base car, so i did my own fitment check. the 18x10.5 fit front and back, the 17x9.5 fit front only. im running 305/30/18 on front and back( fit fine) no rubs! the 17's have 295/35/17 on them and i know i should run them on front because they are shorter than the rears but they look sooooo small. and it seems like on my 2008, 2002 having all the same tire size does not hurt anything. these setups are for auto x's and not for show.

A setup that is wide but not extreme:

Front, 9.5" wide wheels, 51mm wheel offset, and 265 tires (or to reduce stagger the 275 tire sizes are still spec on the 9.5" wide wheels)
Rear, 11' wide wheels, 74mm wheel offset, and 305 tires

But the TSW rear wheel offsets are 65mm and that's probably too far outward for the 305 tire size.

The 2014 Cray line is coming out with the correct wheel offsets for 305 tires on 11" wide rear wheels.

http://www.craycorvettewheels.com/co...ims-brickyard/

Oz has this in a Superleggera III at about $900 each:

Front, 19 x 9.5, 59mm, use a 5mm spacer
Rear, 19 x 11, 74mm
Rear, 20 x 11, 74mm

And the BBS RS-GT:

Front, 18 x 9, 54mm, $900 each
Rear, 19 x 10.5, 75mm, $1320 each

Also, there are Forgeline custom orders at about $1400 each

out a little going from 245/285 to 315 front and back , the tires have to go somewhere! lol- but they dont rub, truth be told i still might go with the 17x9.5 on the front with 295/35/17's just so i have that 1/2 inch higher in the back thing going on, but i dont have to, the 17's do bring the front tire in all the way, f.y.i. who would have thought all the wheels i brought for my 2002 back then would be on my 4th vette sence.

I have 18's all around with 18x6 front and 18x11.5s on the rear with a 325s for the drag strip. I can get any of you guys a set if requested in various sizes since they're 3pc. I just did an 18x10" square setup for a new C7 owner earlier today!

I have a spare set of base painted wheels and found that 19" drag racing tires are hard to find. My C6 automatic launched very well on stock tires. We'll be racing here in a few weeks so I will see what I need. The 18" tires will give an effective 5% axle ratio gain.
