Just installed a pair of these and brackets in my 04 Cobra Convertible... I didn't think i could find a better seat than the factory ones, boy was i wrong. These are even more comfortable and supportive. Being 6' 4, these seats sat me lower in the car, providing more leg room and better shifting, they weigh far less than factory seats as well, and i noticed slightly quicker acceleration to boot. Bolted in using factory hardware. I couldn't be happier with them, i plan to add the heater feature in the near futureas well as a submarine belt slot.
