Look up scrub radius.
Your alignment specs are for; straight ahead only, and at the factory specified ride height only. At all other conditions, the alignment is GONE.
If the camber changes, then the toe-in changes automatically.
If the toes changes, then the camber changes automatically.
If the suspension height changes, then Both the camber and the toe change.... automatically.
With a non stock scrub-radius in the mix, that just throws a bigger monkey wrench into the game.
You asked;
Up to 55 I didn't have an issue with the feel but the speed limit here is 65 on this highway and there was a pretty good gust hitting me at an angle. It was a little unsettling is all I will say for now.
What should that feel like if everything is set up OK?
It should feel rock solid, with no hunting, no wandering, and little to no sensitivity to moderate crosswinds whatsoever.
The Power-steerings are usually a lil over-boosted, but that just affects your perception. The reaction springs are just too soft. The honking big steering wheels usually relax that feeling. The Steering box has a slow spot on center, such that the steering is supposed to be less sensitive there, that is to say, you have to turn the steering-wheel more to get anything to happen at the tire. This is normal and makes straight-line cruising more relaxing, they say.
If crosswinds are bothering your car, and the tires are at a reasonable and balanced pressures, then you can bet the camber and toe are changing with every gust, causing the car to self-steer; this is NOT normal unless; 1) your front shocks are wore out and/or 2) you are running Slanty T-bars with a V8, and/or 3) your rear suspension is swaying about, usually due to one or more of; too high, too soft, or the bushings are shot, one or both of the shocks are shot or yur tire-pressures are very low.
A crappy scrub-radius cannot be compensated for by any alignment changes. It can be affected, but not cured. I know because I used to be an alignment tech, and on my car I tried everything, to use a set of nice offset front wheels I had. In the end, I went back to Zero-offset wheels and the correct height tires, which brought the scrub-radius back to being tolerable.
If your scrub radius is too far off, the tires will want to climb up every elevation-change in the road. The tires will exploit every looseness in the steering and you will be chasing after the wander from one side of the road to the other. As you are doing that the over-boosted steering will drive you crazy. You will crank up the tire pressure ever higher to get the edges of the tires up off the road which on a flat concrete road will feel great. Then on an asphalt road, there it is again......
Ok so those were MY problems. I fixed them one by one. But I won't tell you how many times my car was on the rack, lol. If I would have had to pay for that, it woulddabin a lotta, lotta money.
I wish you better luck.
