Dropping off my car in a few days at the Porsche dealer to get my PSS9s installed. I plan on going with 4 in the front and 3 in the rear with 1 cm rake. Anything else I should tell them when I drop it off? I assume they can cornerbalance too ... if not I guess I'll have to find somewhere else. As far as ride height, I'm not into the low rider stuff ... should I just tell them to drop it about 1 inch and then just make sure there is 1cm rake?
