I'm not sure what the camber is with the Whiteline LCA since I also have GC camber plates and currently sitting at -3 for camber. I believe the difference might be from the cast-iron and aluminum hubs for fitment. Since a friend friend with a MK6 GTI tried to fit the Whiteline ball joints on his car and they are rubbing with his BBK setup. If anyone is interested...I do have a set of Whiteline ball joints for sale for cheap, however they do have scratches on them from the rotors rubbing up against them.A quick comparison on my end shows the Whiteline LCA's have a lot more caster and less camber than what you get with the SuperPro's. It's either that or the difference between the cast-iron and aluminum hubs, but I'm more inclined to believe it's down to the design of the LCA's. For reference I'm also running 355's on my ST-40 kit, so at least that helps narrow it down some.
