No suicide doors, no Lambo doors either. Keep it clean and uncluttered. No need for tons of video screens. It is a sports car, go with a sports car theme. Electronics add weight, weight is unwanted in a sports car, therefore would create confusion among true auto enthusiasts. You should concentrate on upgrading the performance and sportiness of the car. You could add a carbon fiber interior to save weight (looks good too) and trim the center of the seats with Alcantara because that would imply that you did so to increase seat grip from high cornering speeds. As for the guages on the pilars, I say no, too ricey and cluttered. A better option would be to include some small guages in the console somewhere.

Your wheels are huge! Maybe a smaller wheel, more tire, and lower suspension would add to a sporting theme if you decide to go that route. If not, consider some spacers for the rear wheels. Yours has the same problem that many do when adding aftermarket wheels, they need to come out a little more.
