Hell, with a GTS you have a decent amount of room. Try packing in a RT-10 or SRT vert! Just my helmet bag takes up a decent amount of available space. Before I started trailering the car to the track, there was no way I could take a passenger. Helmet, Hans, basic tools, extra oil, brake fluid, air tank, etc took up every bit of room I had. My fold out chairs and clothes had to go in the passenger seat.
