Weird issue

[rabbitude]

I am having a weird problem with the front suspension on my car. The car drives straight and perfectly on a level road but whenever I drive over uneven road, even more so at low speed the car pulls to either side. It feels exactly like torque steer in a front drive car, I have to grab the wheel firmly to keep the car straight. The car seems to folow ruts in the road. I have owned a bunch of other E30's and never had this problem. Heres some basic specs on the car

H&R race, billies, UUC camber plates, cabrio 21mm front bar and IE 19mm rear.

Any ideas on what could be causing this.

What tires do you have? Wider and stickier tires and lower profile tires will do that, they like to tramline.

Isn't that what people call bump steer? if the car is too low with no correction in steering geometry the car will do that.

also if your sway bars are to stiff for your spring rate its will cause this, but with the h&rs it shouldnt cause too much

I have the same problem as you.

Lowering the car causes that.

What is the condition of the front and rear suspension (control arms/bushings, tie rods, RTAB's, and subframe bushings)? What is front camber & toe set to and do you have offset CAB's? Have you checked the camber and toe on the rear wheels?

A lowered car in general, but especially in this configuration, is more sensitive to minor flaws in the suspension. The cause of this could be the front suspension, rear suspension, or a combination. My guess right now is that the rear camber and toe are not the same left to right and you are getting camber thrust. But that is just a guess.

The rear of the car was in perfect alignment when I bought the car a few months back. To the best of my knowledge all the components of my suspension are pretty new. The only thing I can think that may be causing this is the camber in the front. When I had the springs and shocks put in the guy set the toe but did not have time to set the camber. The front camber is set at almost 3 degrees, I just ordered a set of drop hats and was planing to set the alignment properly when I get those in.
