All I know is that I bought 23mm spacers for front & back. I have the 305series tires in the back and they fit no problem. The fronts are close but no problem. Right now my car is on my hoist with both rear wheels off as I fight to install my exhaust. So Monday I can put up a few pics.

As for performance/looks. I did it purely for looks and it does look sweet! BUT, I think 23mm is too big for the front because the front end 'hunts' to one side if I hit bump but the rear end feels planted like Homer Simpson's *** to a couch So I'll probably end up selling the front spacers for some smaller ones.

I think it's the other way around - when you go from 67mm (C2) to 51mm (C4) you ADD the spacer. When Porsche puts the 67mm offset wheel on a C4 they add a 17mm spacer to get it closer to the 51mm offset designed for the C4. The 67mm offset is for the C2.

Pardon my ignorance. The turbo wheels offsets are ET 56 fronts and ET 51 rears. So what happens if you try to put a turbo 19 x 11 wheel with a 51 offset on the rear of a C2S? Wouldn't it bring the wheel edge out 16mm? Are you saying one would need to add a spacer?
