Autox, those bump stops are poly units from summit...I'll try the 3/8" round ones later...It just seems to me that having it that low, the car "feels" softer than it does with the adjusters screwed in a touch more...the T-bar rate doesn't increase when I preload them more? I thought that when you crank up the T-bars, the ride would get stiffer...or is my thinking all jacked up?
