I park my CF inside and it has 1900 on it, I bought it last Nov. So you see I don't drive it very much. Most of the summer it set in my cement driveway on astro terf mats. When parked in the garage on the mats I had no problems but my first outing after parking it outside I noted a thump at 35 mph for about 20 minuts. I got into the habit of stoping just short of my mats and letting the CF set for about 20 minuts then backed it on the mats and covered it up. This helped cut down on the thump. The CF is back in the garage and no more thump even when I move it in the garage stright away. I always check tire pressure before I drive it.

I have a picture posted in my album of how I winch my CF in my side of the garage. I needed to leave a BIG space for the wife to park and she still hits the deviding wall at times. And no she does not drive MY CF. :lol:
