I had my PSS9's put on about a month ago so here's a quick review of my thoughts so far. The ride quality is very nice and is noticeably different than stock. The handling is much tighter which gives me the feeling that I have more control of the car. In-town driving around high speed turns the car is definitely more planted with less roll. I haven't had the chance to do any hard cornering yet.
I've had to adjust the rebound setting a few times to get my desired feel. I'm currently at 7 front/rear and will probably stay between 5-7 just for the reason that the roads in Atlanta can be a little harsh. Even at 7 it's quite stiffer than the stock suspension.
I've had to adjust the height twice so far since I was getting slight rubbing on the rears. The ride height is very low but I am now not getting any rub. The BBS CH wheels are 19"s and I'm running 5mm spacers up front to fill out the wheel fender a little better.
Sorry about the not so good pics. I took the pics at the worst time of the day with sun at noon overhead. Comments on the ride height welcomed. Too low or looks ok???
