Are you referring to + or - camber?

 

neg. camber

 

I just got Polly back from having the alignment checked after installing H-Sports. The rear camber was -2.7 degrees which is somewhat outside spec.

I had hoped that the "adjustment" available in the 2006 control arms would be enough to fix this, but they were already at their lowest adjustment (they could be wound out to -4.5 degrees though ). Anyway, I had bought some Alta adjustable control arms previously, so we threw those on and now everything is back in spec (-1.9 degrees for rear camber) include toe.

And by the way, there is no rubbing for the standard sized 17" tires.

 

My '06 MCS was running -2.7 deg camber in the rears after mounting the TSW lowering springs (which have a fairly conservative drop). My car is pretty heavy (lots of options and gear).

I'm adding the h-sport control arms (I like the urethane bushings for comfort and the zerk fittings for easy lube when greasing my H-sport rear swaybar) to dial the rear camber back to a setting that won't destroy my tires on the street. It's an easy adjustment, so I can always dial more negative camber in for the track and set it back before going home.
