With Unique (great choice, by the way) get the factory installed soft top and tonneau cover. I did it myself and it can be a bit of a challenge to get just right. I had no plans to track my car so I decided not to go with a rear sway bar. I did a lot of research on that one and particularly the Jaguar experts advised me to leave it off. In spirited street driving on very twisty roads, the small amount of extra compliance in the rear gave me a beautiful, supple ride and allowed the IRS to stay planted and really do its stuff. Most people here will disagree with me on that and if you are planning to use your Cobra on the track, the extra stiffness (harshness) in the rear is probably a worthwhile compromise.
Other items - cockpit adjustable brake balance bar, Speedbleeders for the calipers, footbox heat shields and knock-off wheels. Most Unique owners also upgraded to a 16" puller fan on the radiator for extra peace of mind. Are you ordering a turn-key build or a roller/pallet kit?
