I've been looking into the Eibach Pro Kit springs for my CL9 and it seems to be a promising option, but I'm getting mixed answers on whether or not I'll need to fix up my rear camber for it. Called up two shops in Melbourne, one of them said I'd be fine without it, the other said I'll need it. Do these springs really put the rear out of whack? Surely the guy wouldn't be lying as I've heard it's a reputable place.

I'm on a budget so I'm trying not to spend too much, just want to get this thing lowered without paying extra for things that aren't 99% crucial.

Cheers.
