hey whats up guys....
this is my first post so go easy...

i dont have a g8 YET but soon will...
i already test drove a GT and >>>>:eek2::drool:<<<<<

yea....

i wanted to know if 20 x 8.5 with +35 offset would fit....
and what would be the widest tire i could fit on the back with that configuration....

THANKS

20x10 rear and 20x9 front fit no probs......i can't answer the offset though, but you would have to think there wouldn't be an issue there either.

not too sure about the offset as HSV use different brakes with a staggered offset on the rear, but HSV's use 20x9.5 with 275/30/20 tyres. and thats a factory size! surely could go bigger and wider.

Not much room for rubber but yeah, you could stuff 20's under there.
