A suspension/rotor question?
 

So I was on the highway today hitting about 65-70mph and I noticed my steering wheel started shaking more than usual. I slowed down to about 50 and it went away. Accelerated and the shaking was back. Are my rotors warped or is this normal for our suspension? Any idea as to what it could be? Thanks in advanced guys!

An out of balance wheel can cause this. Maybe a wheel weight fell off?

Make sure it wasn't the road.
Then check the lug nuts.
Then get your wheels balanced
