I have the 18/19 stag setup and I am running a 295/30/19 on the rear. You will need 25mm adapters and then your good. Go for it man if you dont like it then sell them to me. LOL

Have you or anyone else had this pebble with there wheel fitment?

The staggered width isn't a problem.

You'll need a decent-sized spacer/adapter because the Corvette wheels are very high offset. I'm not crazy about doing stuff like this (I HATE adapters, and the Lexus cars are very sensitive to hub-centricity) and I'm a self-admitted wheel snob. Staggered diameters look weird on cars that weren't meant for it; some of the MR2 guys do it and it looks very odd to me.
