Is there anyway to get some rear steer out of a 1980 malibu metric chassis with the stock upper and lower control arms? Any such things as a "cammed" bushing or something like that?

90 ford taurus rear controll arm allignment bushings they work well for a little rear steer you might get an inch if you put them in both ends if you need more then you can put them in the outher side to get anouther inch good luck

Consider the attachment points of the lower arms on the rear end and on the chassis. Think it thru and you'll soon see how the inclination of the lower control arms affect the position of the rear end. As the chassis rolls you'll see that both lowers make an arc. You want the left side arc to pull the rear forward and the right side to push back. You have to find a happy medium between the bar angles used for forward bite and the bar angles used for rear steer.

Are you talking about rear steer- just changing the thrustangle by leading the right side or trailing the left side. or are you talking about roll steer where the rearend steers to the outside as the chassis rolls over.
dirt_freeks method just changes the thrust angle but keeps the roll steer close to stock.
eljojo2 method is actual roll steer just like on the dirt latemodels. just not as dramatic.

Yah roll steer is what I'm after. Have you ever heard of guys having their rear axle actually steer a little bit to the left of centerline. For added bite around the corners. Keep the rearend more in line with the front. ???

First thing to do is soften your bushings in the rear arms. Use your imagination. The softer, the more they will allow movement back there. Too much movement and you will push in the middle or off.

One regular poster on here mentioned to drill holes in the desired bushing to soften it up and allow the movement.

Put more angle in the lower trailing arms with the front higher than the back. as the car rolls to the right the left will pull ahead and the right will push back. either raise the front mounts or lower the rear mounts at the axle.

I read one of eljojo's posts a long time ago about "adjusting" the upper and lower angles of the control arms, and decided to try it out this past season. First we moved the lower arms back (giving more upward and forward angle to them. The car pushed so bad, I didn't think I was going to get it back in the pits. Moved them back like right now. Then decided to try adjusting the top arms and their angle, so we removed the bolts at the rear end housing and bolted them back up in the forward position (we had pre-drilled holes in the upper arms), which increased pinion angle and the angle of the upper arms. Went back out on the track thinking I might hit the wall this time. The car hooked up like nothing before. Talk about forward bite! I am a believer in tinkering with the angles and lengths now. It was such a major difference. Thank you eljojo!

Back to my question before, does anyone ever try to achieve roll steer where the rear axle turns a little bit left of the center line? Just an idea. Maybe it would tighten up the car too badly.
