My first thought is why I don't like aftermarket wheels, cheaper ones bend easy, all of them are more of a universal fit so they take more effort to ensure a quality ride. The correct hub rings, a quality wheel, a quality install, and the fact that 99% of places that will work on the car are uneducated or don't care about proper install.
Its my pessimistic view that aftermarket wheels are a crap shoot unless you are going to spend good money or buy something OEM.
