I've an opportunity to obtain 4x18x10.5 Speedlines for track work, but I'll need to sell the fronts, too. Is this worth it to run 315s all around or should I just stick to two stock sets of wheels with 275/315s?

Is it worth the effort?

Thanks,
TomK

My friend wants to pick up a pair of 18 X 10.5's, so if you need someone to buy 2 of them, PM me.

The 315/35/18s may be a little large for the front. I ran 4 315/30/18s and had a little rubbing on my DRM brake ducts but not as bad as when I ran 315/35/17s all the way around. I also got a little rubbing against the top inside of the right rear inner wheel well liner.

I run a C5Z and a C4, but I run the 18" fronts. I like the 18"s since I'm cheap and it's easy to find scrubs in 18". And if I go BBK I'm already good on clearance. Ed

I've got a set of 2 18"x9.5" chrome C5 Z06 style wheels for sale if you need to go down a size. They are on the C5 parts section.

I just went 18" all around with the OEM rears, currently have 305/30's on the front and it looks like I might have a tiny bit of rub on the outer fender lip (bumpy course). I plan on running 295/30 and 315/30 A6's next year.

Cheap, light, clears BBK's, easier to find scrubs ... I think the OEM rears are a damn good option.

Awesome replies, thanks so much. I don't plan on going to a BBK anytime soon, so that's not an issue, but I'm not interested in dealing with rubs or fitment issues.
I'll probably just go 275/315s on the extra set of stockers I have.
Be good,

You will need 18's all around if you have a C6 (to clear the calipers) but you can use 17's on the front if you have a C5. 275's are plenty of tire for the front for most people.

C5Z here, no issue running the stock wheels.
