Steering wheel shuttering at 140kph
 

I'm getting a bad vibration over 140kph in the steering wheel.
I thought it was something with my stock wheels. I bought new rims and it was marginally better. Balancing did a little bit, but still have a vibration.

What should I check,
Any similar problems from others?

my car was shaking at around 85-95 MPH,..I had the Alignment checked and then aligned and it helped a lot,..Frank

Check tires for uneven wear.
Check front suspension.
Check steering rack and tie rods.
Check alignment.
