We are definitely interested in following up on this, because this does not seem normal. Are you able to post the complete details of your setup? Wheel sizes/widths, offsets, weights (if known), the tire sizes you have been running, any mods to the car, and anything else you can think of that might be relevant.
Also, please email me with your order information so that I can note these issues on your account and double check on what we sent.
