i am supposed to pick up some rims tomorrow the problem is the seller doesn't know the offset of the rims, so my question is if there is any offset that will NOT fit on the 04 grand prixs with comp g package (red brakes)?

The rims are 245/35r20 which is an exact fit to oem specs.

Rims are msr 085 style

update after looking up specs for these rims offset is most likey +38 or +40mm should this work?

thanks

Rims are 20x7.5 pretty sure but there is a slight chance they could be 20x8.5 should a +40 offset work with these specs on a comp g?
 


have confirmed the rims are 20x7.5 and +40 offset need to know for sure if these will fit on an 04 comp g as i am picking these up tomorrow
 


I'm running a 7.5 42mm wheel, close to 40mm diff to stock for you, pretty flush, though I'm actually considering spacers for a bit more of an agressive look
 
Yes they'll fit. I don't think that will be flush at all tho. Don't know how that would be. It'll look good but you can't say that will be flush. I have 7.5 wide +25 offset... In the front I'd say 7.5 +30 would be perfectly flush. But then again that car may have a little different fender space. I know on my back I notice there's like half an inch difference from side to side. Go figure, GM and they're good tolerances.
 
You do realize the lower the offset the more poke it'll have. Since around a 35mm offset sits pretty close to flush a 40mm will as well.

Yes which is my I said a +40 won't be close to flush at all if compared to mine a +30 would be flush, if not in some actually. So that's 10mm further in, roughly 4 tenths of an inch. Which is a HUGE difference in look. Your not gonna really see it in a picture but in person you definately can
 


Yeah I imagine they're probably a little different. But as for just wheel fitment, just saying pretty sure +40 isn't flush on a 7.5" wheel
 
Yea. I misread the part about it being a 7.5 rim. Either way there's always spacers and he's lowered iirc so he may decide to run a bit of camber but I'm they'll look better then stockers after its all said and done :)
