The Senna GTR is a full-blown race car meant for the track and has the aero kit to match. DarwinPRO Aerodynamics set out to replicate the wild wings and scoops of this machine on the 720S, and honestly nailed it. The $18,550 kit is the real deal and changes the entire look of the car. Starting at the front, the Senna GTR kit adds a carbon-fiber splitter, new carbon-fiber headlight surrounds, cool-looking canards, and a new carbon-fiber hood that takes center stage. The side profile also changes thanks to a new set of side skirts with more aggressive ducting.
