tire heights will not be correct and will kick off the ABS and have incorrect speedo.

i have the 17/18 C5 wheels on my car. the front is correct at 245/45-17. the rears need to be 285/35-18 to maintain the same overall diameter front to rear of 25.7" tall and not affect the speedometer.

not knowing what wheels you are using, the factory C5 rear wheels needed a little banging of the inner fenderwell to not rub.

actual factory c6 z06 wheels, or aftermarket reproductions? the afteramrket ones may come in a 50-55mm offset which should be fine. factory ones will rub.

They are aftermarket. And what do you mean it will set off my abs light?

nah... I have 18x10.5" C6 wheels on all corners for street.
Works perfectly.
I'm using a 1/4" spacer in the back... and none in the front.
Actually the front is none, because of the huge Porsche brakes... it has the equivalent of a 1/2" spacer if you use stock brakes.
I can take pix on the week-end to show.
