The side splitters streamline the boundary layer at the front section of the short-overhanging Roadster , making it easier to remove air from the tire housings and improving downforce and brake cooling efficiency without increasing drag .

3D canards, which are common among top teams in Super GT (formerly known as the GT Championship) , can also be installed as an option . These bolt-on items generate extra downforce , so you can remove or install them depending on the driving situation.
