This might help you. Spend some time investigating but I would just run 18"s. They are cheap enough to find.But would 17s fit on a GT? I know the GT has bigger brakes than the EB.
That's what I did, and now have two identical set of wheels. Now wonder if I should have gotten a different set for a different look in winter.Buy a second set. You can get stock wheel in the for sale section for next to nothing.
