Ofcourse some major arch flaring them Gt arches will cover them.

You're in denial I think mate.. there's simply not enough material as standard on the arch to get em that wide. An yeah as Mclovin said, no way are you gunna get GT arches on top of them! I run 7.5's on the front of my car with the arches flared as much as possible an they still aint totally covered! 8.5's are gunna be a nightmare aha.

JDM arches as those linked should cover them but pulling them off with the car is a different story though. Give it a try though nice to be different.

GT arch trims and standard arch trims will not work.

Could look cool though.
