We put the Pro-kit on the wife's P5. I thought the car handles well before the install and it was even better afterwards. The ride is a little more harsh, but I don't think it is that bad. The car also has Nitto 555's on it which also has an effect on ride quality. The overall appearance of the car with the kit...AWESOME!!! My wife was tickled, she let out this silly giggle and a great big grin. The installation was not bad at all. She helped me out and it took about 2.5 hours to do all 4 corners. It prolly would have been a little faster without her, but I was glad that she wanted to be involved with the whole deal. She has now helped do the speaker/dynamat install, Injen intake, B&M short shifter/MOMO knob, and the springs. Oh well, I always end up rambling in these posts. (doh)
