Thread: What offset will fit 04 gtp comp g?

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
