Steering Issues

[Siq67Lark]

I've replaced every part of my suspension (went with coilovers and fully adjustable arms and have new tires and wheels, aligned at -1 camber all around). The car sits very low, which I like, but on the freeway at 70 or more, when I go to make turns the car wants to pull me all over the road. The turns are just the gradual ones on any freeway to get around hills and such, but this issue is pretty serious. Before my alignment and bump steer kit was installed I used to get thrown all over the highway and change lanes without moving the steering wheel and this isn't nearly that bad, but I know it's still not quite right. At slower speeds around town it is perfect and I never have an issue and even up to around 65 everything is great, but cruise control at 70 is my problem. I've checked all my suspension parts and steering and nothing is loose or damaged and my tire pressure is 32 all around and the tires are basically brand new. The only thing I haven't replaced yet is my rack, but I would imagine that it would give me problems more often. I've never driven a car that has this tight of a suspension set up and was wondering if that might be the issue? If it makes a difference I do have power steering as well. If you know anything that might be able to help me out I would greatly appreciate it and if you need any more info just let me know. Thanks in advance

Sounds intristing if ur arms are adjustable and u got an alignment, then im guessing its coming down to ur tires? Is ur toe set to 0" degrees?

I believe so. I didn't ask when I got the alignment, but I'm assuming it was. There is no premature wear on my tires and it handles great other than at freeway speeds

Perhaps your coilovers are too hard? Is the road you are driving on bumpy? This can cause a lose of traction if the coilovers are too stiff. Might want to adjust them to a softer setting.

I'd say bump steer kit was not enough to correct the front bump steer problem. It really is delicate, you can't eyeball it.

Anyway, it should not be that violent, and i remember having that problem too. it was corrected by having the rear traction arms at a correct length (the lower you go, the longer they need to be, it creates rear bumpsteer when it is not).

I also had badly preloaded the front anti roll bar when setting the ride height (i did not unbolt it).

I corrected these 2 and the car went on way better. I also had some steering rack issue, caused by not that straight wheels, but the car never threw me around because of that.

You can also check if everything is still correctly bolted, and if someone did not mess with your coilovers damper settings.
