C55 vibration in seat/floor at 65+
Hi guys,
I always had a very mild vibration on my winter tires. I just had my summer tires mounted and it's gotten much worse. At 65mph, it's very noticable in the seat/floor board. I do get some steering wheel vibration as well but it's a bit more mild there.
The steering has been off center for a bit and the car will ever so slightly pull to one direction, but I often think it's just road crown.
Anway, I have 130k miles on it now. I'm thinking about having them road force balanced (the tires I just put on were not balanced on a road force) and having an alignment done.
Would it be worthwhile to replace any suspension components that could also be causing the vibration/would make sense to replace before getting an alignment done?
I just got done replacing the motor and trans mounts this past weekend...not a fun job but idles much smoother. Now to figure out my at speed vibrations...

I would start with a balance and alignment based on the above. I would not just go replacing anything. Have someone you trust take a look at the car and see if there are worn parts.
