as some of you know I have an 06 focus and had tein the wrongs ones on and was ok(06 has different suspension then the previous models), then I went to sportline and they were crap. Can not find their way over any pavement, they ride really unevenly because of them being progressive. Now I got the prokit and is ok, but not stiff, a bit more then stock, but feels loose. did I mention with all of them i would bottom out, less with the prokit... is the intrax ok, worth getting, they are available. i Would really prefer the hr race kit, but is in R&D. BTW, I got HP from Tokico...
I haven't used them myself, but they were one of the only kits available for my Sebring when I had it and the guys I knew who had them weren't unhappy. I was going to get them but got rid of the car first. At any rate, I never heard about poor handling or broken components from the guys who bought them so I wouldn't be too concerned.
