I have a set of 225/50R16 tires on 16X7 Panasports on both of my Zs. I think one set is +6 offset and one is 0 offset, but I got both sets secondhand. After mocking up both sets on one car, I think the tires make a bigger difference than the slight offset (although that helps). The RE-11As on the green car are quite a bit "bulgier" than the Turanzas on the orange car.
The facts...
- Orange car is on +6 offset with very old 225/50R16 Bridgestone Turanza rubber.
- Green car is on +0 offset with 225/50R16 Bridgestone RE-11A rubber.
- Green car has +0 deg of rear camber, orange car has -1.5 deg.
- Green car has trimmed rear arch lips and front valence
- Orange car has aftermarket air dam
- Zero rubbing on either setup
- Switch sets between the two and fatter rears will rub on orange car
