Almost all cobras have a solid shaft connecting the steering wheel to the steering rack. The "rag" joint that our daily drivers have help dampen the effects of the front tires. Also as mentioned above we have light cars with big tires so any road or tire imperfections will not be mashed out with weight. Put your tires on a SUV and the shimmy will not be noticable on that vehicle.

I am running 17" Kumhos and I have very little if any shimmy. Maybe the lower profile performance tires are truer than most "S" rated tires?

I had a 1998 Honda Passport(Rodeo with badges) that had this same problem and the only way Honda could correct it was by putting better quality tires on and having them trued(shaving off high spots) and balanced on the car. After that the ride was like a caddy. Before the tire truing and on car balancing it was so bad at times my hands would tingle. The only problem was if you rotated the tires you had to rebalance on the car again. I suspected it was a bad set of rotors so rather than deal with it I traded for a Car. It was a shame as other than the shimmy/vibration it was a great vehicle.

If you are having a problem on your cobra find a shop that does on car balancing and tire truing and you will be suprised how much better it rides. Rotation of tires on a Cobra is not a option anyway.
