I have a set of Boyd Coddington Magneatos from my last vehicle. I can't seem to sell them, so I was thinking of having wheel adapters made and installing them on the GTO. They are a staggered fitment, 18x8,18x9, with 245's and 275's 45s. I don't think the rear tires will fit from the sound of folks who have tried 275s on the 17s. Does anyone have any advice on this issue? Oh, the wheels are 5x114.3 off of my old 350z.
