Tonight was the first night I got to take out my Shelby for an extended drive with my newly mounted Alcoas. I noticed a pretty bad shimmy in the steering wheel from 45 to 65 MPH. My thought is bad balancing because it goes away after 65 and I don't feel it at all below 45. I don't feel it all the time but I'd say about half of the time tonight that I was between 50 to 55 (which is where it is the worst) I felt it. It is clearly noticeable, if I let go of the steering wheel it will vibrate back and forth so much that anyone sitting in the car can see it moving. So to me that is a balancing problem because I didn't notice that on my stock rims and tires but just wanted to see if anyone else has run into this problem before? Anything else it could be?
I should clarify that it feels like the from wheels are oscillating back and forth from left to right not a typical out of balance there it is a radial up and down out of balance. I think too much wheel weight towards the front face or back lip of the rim would cause that?
