I had the tires balanced. It has helped but its not completely gone. The car vibration is gone but there are is still very minor steering wheel feel which gets a little noticeable around 120kph. I realize now that they did change my front rotors, I thought I was only getting pads, and they are not OEM so that could be my issue. The car does drive fine so I may live with it for a while. My shop can't find anything wrong with the car now.

 

I had those exact symptoms at the same speeds and again at 75mph+ but with stock 16in size. I replaced the inner and out tie rods, strut rods and had wheels balanced. Issue persisted....like an idiot I went cheap and got poly bushings for strut rod. Ordered oem strut rods and now all gone.
