Just an update - I verified that there is no binding in the suspension links, so I'm now looking into my coil-overs. I weighed the rear end of the car (using a 2nd class lever and a bathroom scale) which worked out to 1050# with two adults. The QA1 tech support recommended a spring rate of 125#/in., but I bought 140# springs in case my weighing procedure is off. The springs should arrive in a few days. When I get the new springs installed and take it for a test drive, I'll post the results. I had 200# springs, so this should make a serious difference.
