For you guys that have gone to stiffer spring,and just not getting it done,here is a place in New Hampshire that will do a revalve and from what i understand the turn around time is real quick,but this is for the New England crowd as he is in N.H. the name is AMF Motorsports number is 603-256-6800 or fax 603-256-8142 and from what i hear keep the phone ringing,as he must be working in the area,and have his hands full,good luck and this came from a guy who is on HCS that had his done and now really likes the way it goes.
