2023 WB Shaking At 80MPH
Hello All, I have this issue when I get to approx 80mph the car has a slight shake or vibration.
A little back story, bought the car at the end of 2024 2nd owner from a dealer with 16k miles on it. The car was already lowered using Eibach spring kit. The car came with new stock tires. I ended up getting the car road balanced because we noticed the vibration after driving it daily. It seemed to go away or maybe a slight vibration. Dealt with this for about 10-12 months. Went to change the oil about 3 months ago and noticed the front tires had really bad wear on the inside. Since the car sat so low I never saw this unless you were under the car. Looks like the alignment was way out of wack. The previous owner never aligned it after the lowering kit. I wanted better tires so I bought some Michellan Pilot Sport AS tires and got the alignment. The shop said the front arms were maxed out and they couldn't do anymore to get the alignment in green. After some researching I bought new upper control arms that had more room for the alignment. Took it back to the shop and got everything in green. The back is borderline but it is in green. I plan to buy rear arms next to fully fix it.
So after the new tires, alignment, and road balance the car seemed to have a small shake/vibration. Took it to another shop to get it balanced again. The slight shake/vibration is still there.
Im not sure what it could be now. Anybody have any ideas? I dont know if the wheel balance is the problem now. It seems like it gets better after the balance but that could be just me tripping out. Any ideas are greatly appreciated.
