The Firestone in Montgomeryville, PA not only did the alignment on my 07 Crossfire after I installed the aftermarket adjustable rear camber bushings, they installed the camber alignment bolts up front which I had and provided if needed. I have computer print outs of the before and after alignment settings. The lifetime alignment purchased at that time way back in 2009 cost me $130.00.
