I have did hours of research on how to correct the bump steer on a metric. This is what I have found out. Get a 83 Iroc camaro drag link and shortin it 1.5 inches in the passenger side. Then trim back the outer tie rod on the passenger side to get the toe correct. Then maybe bending the idler and pitman arm down 3/8". Is the all that has to be done. This is assuming ALL STOCK uppers and lower control arms along with metric spindels. Also if I start messing with the front roll center of the car after I fix the bump steer, will the bump steer be off again. In other words should I work on bump steer first or the front roll center.
Thanks

In my opinion I would change the roll center before the bump steer. Are you running a front bar? With these sloppy metric cars the roll center is easier to modify than altering those bump steer components. Also while you're changing the roll center you can adjust the caster to reduce bump steer as well. The payoff of the roll center with payoff more than just fixing the steering points. If you start chaing around those points you'll also alter the ackermann steering as well.

Ive heard of bending down the outer tie rods but not the idler or the pitman, look for some posts made by Awkward Jeff, he was a guru in that area. Eddie

why a iroc center link? why not a z28 link? any one ever tried a center off a rear steer nova with metric tie rods?

I spent about 2 hours looking at all his his post trying to see what I could do. I am going to change the roll cnter first and then the bumpsteer. Ive gotta get out to the shop and measure all the angles so I can plot it on AutoCAD and see what I need to change. I dont know what It is suggested to use the IROC link but I guess thats what worked.
