    Default Bump steer, Chevelle

    How much should i be targeting? Same as a SLM, bump out but not in?

    Also, do you check it at ride, or attitude or both?

    Just trying to get a handle on what people are doing, in my older Mod days we just ran the stock stuff, but it seems nowadays there are many options. Adjustable center links, and idler arms etc. I like the idea of replacing them stock inner tie rods with something adjustable.

    Thanks, Krom

    Just say no...

    FWIW...We run heims inboard and outboard. 1/4" spacer between RF spindle and tie rod, 3/4" on LF. I have not measured that but is recommendation from our chassis builder for 3 piece spindles.

    Thanks Outlaw, heims on top or bottom on steering arm? Our car strange enough, but they are on top, i keep worrying about the tie rod hitting the frame. I do have the dropped tie rod, outpace i think, and stock inner tie rods, but i want to convert it over to a heims on both ends, and the aftermarket drag link, adjustable.

    When i get time this Winter i will run it thru some checks at ride and in posture, and see what it is.

    Bottom of the Arm with the spacer between the arm and heim. We also use the extreme clearance outpace rod. We cant use the adjustable link.

    We also just drill out the steering arm for 5/8, then use a bolt.

    try and set the bump for a littlie as possible but make sure if you have a change in the bump it is adding toe out in that wheel. As for checking it best to use the setup up plates I build and then put the chassis in dynamics . When you use the setup plates and use floor jacks to put the chassis in dynamics that will let the chassis move as if it is on the track. remove the RF spring please . On most rf corners of the chassis the frame moves down ,forward, and to the left so then all the pick up points end up moving aswell changing the settings in the front end. and make sure to put chassis hike in the LR.
