*As a caution*
The car has to go back to the shop next week so they can custom extend the adjustment in subframe and create slots in the rear for full front/rear camber adjustment. The only kind of place that usually likes to do jobs like these are performance shops so keep this in mind. Once you go beyond a certain point in ride height any shop won't be able to fix any camber you induce with the OEM camber adjustment points.
I hope they're not drilling the stock cast aluminum arms. The reason the there is no rear camber adjustment is the arms can't be safely modified. There is a very good chance of hitting an almost microscopic void in the casting causing the arm to fail. There really isn't enough material in the rear arm to safely elongate the hole!
PLEASE..... BE VERY CAREFUL!!!!
