Mostly self created but let me run down what I've done and what I want out of my car(93 gt)

I had a coupe at one time and ran drag springs with Lakewood 90/10s on the front no sway bar. The wheels were stock ponies. Many people said that suspension would be murder on the street but I never had a problem with it even at sustained highway speeds.

Now I've got the GT with stock springs/struts and skinnys (weld draglites) up front no sway bar and my front end is all over the road at highway speeds. I want to correct this. Will putting the sway bar back on fix this issue or do you all think it has to do mainly with the pizza cutters? I want a tame daily not an all out drag car like I had on the coupe.

How are your tie rod ends and steering rack mounts? What's the current alignment settings?

...before 15 people come in and says you definitely, absolutely welded your subframe connectors on with the chassis crooked...

Tie rods are new and so is the steering rack. As for the alignment all I can say is it is stock caster camber plates on the towers and had a pro align it. Car tracks straight and true and tire wear is nice and even. Subframes aren't welded on crooked since I don't have subframe connectors.

Well, this is an easy problem to solve. Borrow a set of front wheels & tires to verify.

Personally, I suspect that the problem is worn out suspension or steering components. These cars track just fine on skinnies if the suspension is working properly.

I bought an 88 GT. Swapped out springs, Eibach drags up front, has MM adjustable lowers in rear. I pulled the sway bar up front, added new skinnies and drag radials, replaced the rack (leaking). Car finally sits the way I want it and LEVEL for once. I hadn't really driven the car before the work. So I drive it... tracks nice, don't pull etc... BUT it is all over the road like it has a low tire. I thought "damn skinnies and drag radials"! I jacked the rear pressure way up to see if it helped. Nope. So I finally found it. Rear lower torque boxes are cracked! Car has bolt in sub frames but I put upper and lower torque box reinforcements in it. I bought full length weld in subframes with the seat brackets and rear torque box reinforcement plate. Look at your torque boxes, pull the rear seat bottom and look for broken spot welds.

Good call on the alignment specs. If you still have your factory plates up top, that means that technically your caster and camber were probably not adjusted, only checked. The camber could have been adjusted with some crafty bolt kits etc but I doubt it. So essentially what you got was a "TOE AND GO" alignment, meaning that they adjusted the toe, said poop on the caster and camber. Most cases camber causes a pull if its way off from one side to the other, and camber would have to be pretty bad to cause a loose feel on the road. What I'm saying is that with the factory top plates on the car still, I doubt it is off far enough to cause the loose feel. Toe will cause a loose feel if it is really negative but I'm thinking even the laziest alignment guy would have set the toe pretty close on a new rack. Its just easy. Not saying it couldn't be an alignment issue, just saying I doubt it.

Thank u for all the sage advice! I have no idea how to check the alignment but if one will tell me I will get right on it and get back to you all. Torque boxes are perfect, one of the first things I looked at before buying the car. Front springs and shocks are brand new along with the bushings in the top of the tower. I tell you though, you have me thinking about the rear springs which I haven't touched(new shocks out back though). The springs are red eibachs I believe. I was recently under the back to put some sve rear upper and lower control arms on the old girl but I had the problem before those went on (solved a rear end clunk issue I was having). When the lowering springs were on the front I didn't have this issue, however, the car was sitting on cobra r's at the time.

It would be an easy problem if I knew anyone that had a fox around me. I have been trying to get a set of two anything off of Craigslist but haven't had any luck yet.

Not much you can do to check it. Have it aligned and GET A PRINT OUT of the results. We can help you to rule it out but only with the numbers. I did many of alignments in my time and lots of guys I worked with did garbage alignments. Just because it was done don't mean it is right. I corrected "it was just aligned so it can't be that" all the time. Not doubting your word either but I looked at my torque boxes before I bought it too. You can't see much damage by looking under sometimes without a lift. And my car had the spot welds pulled loose from the floor. You couldn't see it without pulling the rear seat bottom. The boxes look good but they weren't hooked to the car!

A "tick" like a stone in the tread? Tick tick tick? A wheel bearing will growl going down the road like a "big mud tire" lol. Weld wheels (skinnies) are famous for hitting the brake caliper bolt or the brake pad anti-rattle clip and making noise. Easy to tell, pull the wheel and look for witness marks.
