Howard - thanks for sharing that ride. The wife & I just again started enjoying our trips to the country here in VA and love riding with the top down. As far as shake, I have an '06 with the FD springs installed. I've noticed that when I take the car out cold from the garage, I experience cowl shake w/in the first mile of driving at around 25-30 MPH. But....for only about a minute or less. It seems that it somehow works its way out, or warms up (hmm maybe it's the tires flatspotting till their warm). Anyway, I have had mine up to 155 on the track and she was as stable as if it was 90MPH on the interstate so, I'm wondering if there are suspension or tire issues with those of you that are noticing it all the time.Would like to hear from other spyder owners that have had this minor irritation.
