    this should be interesting.....its time to get to the bottom of the issue, when i do i want to see how many people guess right to the death wobble problem...just for fun :)
     
  2. Hard to guess and thats what it would be without a description of the EXACT issue. When, why,how fast.
     
  3. Over 30# of air and that is part of your problem.

    One thing I never see brought up when this issue is discussed is brakes. I think it's rarely an issue with hot rods, but I've had quite a bit of experience with later model jeeps with the coil springs and "four bar" setup. Occasionally, one of the calipers will start to hang up a little bit, and when you hit a bump or something that lightens the front end, death wobble starts.
    Like I said, it's probably not much of an issue with hot rods, but it's something to keep in mind.

    those were the ones i took off mine. car went from shakin' past 65 or so mph, to a decent ride past a 100. they were just too firm for my car. i ended up using some pro shocks instead.
