Depends on the severity of the shake and vibration. I own #383 and the Cobra does not drive anything like my C7 Corvette or even my '65 Mustang. Wear of the tires on Cobra are good and in perfect road conditions, Cobra is smooth sailing. However in my opinion, the vibration and shake you may be experiencing is because you are in a short wheel base car with big wheels and tire. Lots of rubber on the ground and you are picking up road conditions. I would suggest having a reputable shop check out condition of the front end, steering, and look for tire wear issues. If a reputable shop states all looks good, then it really might be an over reacting.
