    Default Metric bump steer

    Any tips for improving bump steer on a metric clip when using a metric drag link? Iíve tried multiple spacers at the tie rod and canít get anything close to my liking. Using heim ends for inner and outer tie rods. Thanks

    I'm by no means a modified guy, but I do believe most or least some bend the drag link to get it right. Again limited knowledge here but I recall helping a few guy now and then and that's what we did and heard people do it all the time and is common.

    Bumpsteer on s metric frame is contributed to largely by the angle of the upper a arm inner pivot.
    If the pivot axis is largely parallel to the frame, bump steer can be set with the stock center link.
    If axis aligns with the lower inner pivot axis, bump steer is much more difficult to obtain.

    Factory engineers used the caster change to control bumpsteer and the anti dive characteristics to deliver a somewhat drivable product with the tall ride heights these cars were running at.

    Racers use these much different than the factory intended.

    95shaw my upper mounts are parallel with the chassis centerline. (Or close to it.) how close should I be able to get it with a stock drag link?
