There are a lot of grooves and what not around here. While driving, most times you have to hold the wheel with both hands because the car follows any and all grooves in the road. Is there something I can do to correct this? Maybe worn out bushings or something?

Car isn't lowered yet. Has had the LBJ and OTR done in the past year. No suspension modifications.

directional tires tend to follow the road too, if you have them.

My car started doing that the day I put the snow tires on. 2nd season on the Michelins (summers were on their 1st season). I've had the lower ball joints changed too.
So, could be a tire issue. Start with something easy like swapping your front and rear wheels, if no difference, start inspecting bushings.

I have directional Pirreli Pzeros in the front which are a different size than the back, so I can't swap them. I seem to remember my old Kumhos did the same.

Should I change just the bushings or the whole lower control arm? I saw them on Sewell for 340. Is there anything else I should swap out that may help?

Here's little more info on my experience. A couple days ago I drove 30Km on an older highway surface at 120KPH (75MPH) and the car was all over the road. Today I drove 60KM on a recently re-surfaced highway - car went arrow straight.
My thought is, these cars are hyper-sensitive in the front suspension/steering, so even a small amount of abnormal tire wear, or bushing wear is amplified.
Having said that, there is a very long and detailed post on this forum by a member who says the caster arm bushing is the culprit in a lot of the steering issues that plague our cars. I did a search but didn't find the post unfortunately.

Yup, the Pzeros grab the road with awesomeness!!! Thats why I use them, I like the control it gives you. Its defiantly the tires and nothing else. You can give them to me

I had a very similar issue, which in my case ended up being tires. So before replacing suspension pieces, maybe try the obvious? Have a look here: https://www.clublexus.com/forums/gs-...ck-solved.html

The tires still have quite a bit of tread left, but I will check the wear and flip the fronts to see if there is any change before getting new tires.

The wider the tire, the worth the drive on uneven road is. On my sports car I run 275 on the front and 335 backs, the steering wheel requires a lot of attention when driving on irregular pavement.

Most likely as said above control arm bushings and any other weak spot in the fron suspension. My car tracked like that and my lower control arm inner bushing where non existant. GL
