I know, it's mad growing up so fast, he's coming le Man's again this year with me, in the Vette. Hope you are both keeping well. You are right I would be looking at same size or possibly Z06 offset but no larger & I would be keeping the mags.Good grief Nigel, d'you know how old it makes some people feel, seeing Luke with that car!
I like those wheels, but only if they are the same diameter as the originals - can't stand small rims on Corvettes! You'd hang on to the magnesiums I assume?
