    I'm using a piece from Wolfe Racecraft. No pic's but you can get some info at their web site: www.wolferacecraft.com

    Totaly changed my car. I would recommend an anti-roll bar on anything in the 11's or quicker. It really leveled up my front end when lauching and needs very little preload. I went from having 6 inches of air under my left front to having 4 inches of air under both front tires. An added benefit was added stability past the traps under hard braking.

    Good luck

    what is the bar size? Diameter and wall thickness that you used? I just got all my stuf from Wolfe Racecraft, so I can meassure for comparison for you.

    Rob,

    Double check that tubing size, it seems pretty thin. I'm not saying it's too thin or anything because I'm no expert. My Wolfe bar is 1 1/4" with a .375" wall. Maybe mine is overkill. It sure works though.

    Good luck and let us know how it turns out.

    thanks for the concern, I believe that .094 wall chrome moly should be thick enough. I will be checking it for twist periodically.
    I will find out this weekend.

    The anti roll bar I made for my car is made of 1/4 wall chrome moly. I spoke to one of the guys at PRI about their bar and told him what my car was doing with d2 axle steel and he told me all could be corrected with 1/4 wall anything smaller would flex to much in a heavy high HP car. so that is what I did and it appears to be much better than before.

    Realizing this is a juvenile remark, but here it comes anyway.

    I like the idea of an anti-roll bar as opposed to a roll bar. An oz of prevention is worth a pound of cure, as somebody's mother once said.


    How is this different than a roll bar that is intended to keep you alive after a roll? Obviously I'd prefer to stay straight up versus rolling over in the first place. One of my projects is to get the front end of the 72 in my av off the ground.

    Mike,
    The Anti-roll bar we are talking about is the bar installed between the "roll cage" which is attached to the rear end, and desinged to limit the amount of twist in the car on a launch keeping equal load on both rear wheels rather than most of it on the right rear.
    Hope I explained that right.:Smarty:

    To further clarify, here is the anti-roll bar in the Tube Chassis GS we built here at the shop.

    It's the bar mounted above the rear at the very top of this picture, between the frame rails, with the alumium arms and links that go to the rear end housing brackets.

    Well I got to try my anti-roll bar yesterday, and the verdict is.......WOW!!!!. The car launched straight and even. Consistant 60' times between 1.53-1.55. So far so good.:TU:
