I'm new here and have been following for a couple years. I'm looking at dropping my G37X a little.
Anyway...can they make it any harder to understand just what is needed to adjust the rear camber on these cars!! G35, or G37? Straight or bent? With arm and bolt or just a bolt...or arm, bolt, and plate? Sway bar...stock or aftermarket? I also read that the Eibach camber lit is the same as an SPC! WTH!!

 

Direct from SPC customer service:

"72280 is the older part number and the newer number is 72260. This will work on the G37 as well and it comes with the toe bolt as well."

 

So the new arm is the straight bar...that hits an aftermarket sway bar on a lowered car.

 

That seems to be the case.
