Hey guys I am going to be getting the PST polygraphite fit for the front and rear of my Buick wagon. and prob the KYB shocks too, have any of you guys used these products from Performace Suspension Technologies? How do they feel? Also I hear from the shocks post that it is a toss up if the shocks will go on easily or not. what is your expereinces with that install? and the install with the front sispension components, i.e., ball joints tie rod ends etc...
