What are on-center and off-center BMW E36, E46, Z3, Z4?

When ordering an E36, E46, Z3, or Z4 kit please make sure to determine whether you have on-center or off-center top plates before ordering. We make kits for both on-center and off-center top plate vehicles. We also offer camber/caster plates for many of the vehicles that use off-center top plates.
