Car feels extremely unstable going in a straight line

Did you check your rear subframe bushing? My car feels like the rear end is zig zagging when I floor it on the highway and I am 90% sure it is because I can put a finger into the hole in the rubber of my subframe bushing.

yeah all of the bushings look fine, at least to me.. but im not bushing expert either lol

I have 2 different sets of tires on the F&R.. does anyone know if the difference in tread patterns would have anything to do with it? I've been reading some other threads and some people were saying different tread patterns can cause weird handling characteristics...
Here is my front tires
and here are my rear tires

^ Yes to both..
Yesterday got the car to around 80mph just trying to see how it reacts and under hard braking from 80mph, it takes constant counter steering to not lose control of the car.. i took up 2 lanes slowing the car down. Does that point to anything?

Last time my car felt like this was when I put new rear tires on. Took it back to the tire shop and explained to them how the car felt around 60mph & higher. They rebalanced the tires & solved my problem.

I didnt know you had different tires on the front and back. The tread pattern and sidewall stability of those tire sets could be completely different and can cause problems with squirrelyness on the freeway

Yes I am interested as well, I installed coilovers w/ camber arms and toe bolts last week and I am getting the same unstable floating feeling, like my car is just riding on springs and no shocks, but I had the rear subframe bushing problem as I mentioned before.
I am no expert on suspension geometry but would having different ride heights on each wheel cause this? I had a heck of a time adjusting my ride height, especially on the rear. Could barely get the fenders off the rear tires even at maximum height on the springs, and I am wondering if maybe I didn't match up ride heights on them properly. It would kinda be like a chair with one leg shorter, no?
I haven't gone for an alignment yet, so I'm hoping that helps out a bit too.
