Bottom line.... Honda decided to put a more aggressive camber into the rear suspension and it resulted in excessive and unwanted tire wear/cupping. Then, after this issue started showing its negative symptoms they came out with a revision to the original upper control arm. These revised control arms do NOT resolve the issue.
I am currently the lead plaintiff in a class action lawsuit against Honda America. I have been in discussion with forensic experts and other professionals regarding this issue and have learned a great deal regarding the in's/out's of corporate greed and dishonesty at Honda Motor Corp.
I fought at great length to get Honda to correct this defect in manufacture with the end result being stuck with a vehicle that eats tires within 15 to 20,000 miles regardless of revised control arms.
Harvard07 has the right approach .... buy aftermarket adjustable upper control arms and set the camber to '0' as well as the toe.
My deposition is December 7 and I will be back here to share more as its made clear to me. I'm so disappointed in Honda! I bought what I believed, and what they advertised to be, was the MOST dependable car in the world.
I had the control arms replaced by Honda. They did NOT fix the problem.
