In hind sight, I installed Rear Adjustable Camber Control Arms in April 2009 at 57,000kM (2007 Civic Ex). At that time I adjusted the rear Camber to 0.0 degrees and the Rear Toe In to 0.0 degrees and it solved all my rear tire wear problems. Since then I have put on an additional 50,000kM (now has 107,000kM on the OD) with lots of weighty loading and no abnormal tire wear. In short, I am a happy camper.
