Camber should be adjusted OEM in the first place, which isn't possible. I don't know Dinan, it's from the USA. I think I can get some of these in EU too.
I'm a trackday user, as many here may know
(this sunday to the Nordschleife) But sometimes I 'm having a lot of understeer.
REMEDY. NO CAMBERPLATES, NO!
Just buy a 130i M. Or a M3 CSL. LOL
