Just recently took my hatch on a pretty long journey on the highway for the first time. I notice that at 80+ MPH the steering wheel shakes pretty bad and the whole car as well. Its not horrible, but not good either.
I'm pretty sure my back right strut is blown, (its on skunk2 lowering springs with stock struts, not my doing.)
My first guess is that might do it, but it feels like its coming from the front of the car. So my initial thought is I need an allignment. My other thoughts are some bushings are bad or something too.
Should I start by just getting an alignment, and see if that helps, then look into bushings and such?
The car also has a rear camber kit that Idk how accurately was dialed in. Will the alignment shop know how to do that properly?

Thanks for any advice.

Have the wheels been balanced?

Honestly I have no clue. haven't really dons a lot of anything to the car since I got it. That was definitely one of my first thoughts though too.
Ill check into it.

Id say unbalanced tires also. Ive had this problem before and both times it was the tires

I would start with an alignment check, most places will do them for free. If that checks out fine, check the wheel balance. I'm not as familiar with shops (local to me at least) willing to take each wheel off and check the balance.

I've never run into a shop that'll check them for free, but it's cheap, and should be done anyway for the sake of proper maintenance. A lot of shops will also warranty their alignment for the life of the tires, making that $15-20 per wheel even more worth it. Call me ****, but my wheels come off every 3 months for a balance check, while I'm doing my rotation.

Alternatively, don't drive 80.

OP, does the shaking occur both with load and no load after it reach 80?

seperated tires,
move the fronts to the back to test.
very very common, expecially with worn or cheap tires, and we know 75% of people buy cheap tires.

If the shaking go aways or changes dramatically it is seperated tires or a bent wheel.
