Located a 'race' shop that would take on a Camaro (primarily GTR's and Porsches)...and spoke English! Does wonders for communicating desires and confidence in the job.
My old specs on the car (rear is untouched from the factory / the front was tweaked before I left the states). Notice toe out on all 4...explains some of the nervousness and tramlining that I attributed to 285 front tire/20 inch wheel side wall. It drives much better on the street now!
I had front camber maxed (-2.1), rear -1.5 and corrected the toe to .05 in on the front and .10 in on the rear.
Clean shop...got me in on a walk in basis - excellent! Looking forward to see how it feels on the next Ring visit (8 Sep):
Cost was $132 - good deal!
