You are right - somehow I forgot that some ZR1s came with sawblades. The rears only are 17x11, right? Also, good point about convertibles. I don't know if there is a functional difference in their wheel well space, but the OP should measure and verify. FWIW, on my base coupe I can fit 17x11 et50 wheels (rear Grand Sport dimensions) at all four corners with no rubbing. But the sawblades on the ZR1 have et36 offset, which will not fit a base car without flares.

The mentioned 17 X 9.5 (@+56) is the only fit the OP should be considering and the OP mentions '94 so that is a "machined finish" saw-blade and that wheel was only offered in '93 on the ZR-1 which won't fit anyway!

ZR-1 specific 11" wheels are @+36 and the GS are @+50 so the OP can't use most of your information and needs to disregard. The extra width of the ZR-1 rear body allows/requires the @+36 to accomplish a fit/finish to rear body panels.
