The wheels will fit but with 315 tires dont look good on . 285 may look better

Has anyone got ZR1 17x11" wheels on the back of their early C4?
If so, do they stick out past the gaurd?

[Vette Obsessed]

Not personally but if you have the ZR1 offset on a 84-87 Corvette they will be close but won't stick out.

I have some pics of an "early" C4 with ZR1 offset vs non-ZR1 offset but can't upload them till I come back home.

Phil Hyder from Vette Connection (03 97764114) runs 11 inch rears on his racecar, but they are not ZR1.

Well actually the answer is "yes" and "no". It depends on how much negative camber you are running at the rear.If you run to much negative camber the tyre can end up rubbing on the inside,not to mention increasing the wear of the tread.
In its ideal position the rim and the tyres' tread will line up to the edge of the gaurd.

my opinion is that they will fit. also try this link, listing wheel specifications for 84-96 vettes http://web.telia.com/~u60113743/corvette_wheels/

Yes they certainly will fit (I have 95 ZR1 rims on my C4) however they'll fit
as i've described.
