I've got a 2011 G37 with Eibachs and a SPC camber kit installed. I've had the car aligned about 4 times in the last year. Does anybody know why the alignment keeps going out of spec? It's always the rear toe that goes out of spec.

 

You driving over alot of pot holes? Crappy roads? That or the guy doing your alignment isn't tightening up the toe bolt enough. Do you have the SPC toe bolts installed too or just the OEM bolts?

 

I'm not driving over many pot holes. The roads on my commute does have some rough sections, mainly on the off ramps. I've got the SPC toe bolts installed.

 

Were all 4 times at the same shop?

 

At did three at the same shop one at another shop.
