Activities???
Devon, if it's a dedicated track car then I'd remove anything not needed to go fast. This includes wiring, bumper supports, brackets, insulation, interior panels, any accessories in the engine not needed, turn signals, lights (might still need these if running at night), and of course replace all glass with plexi and make the windows fixed shut with no adjustment and weld the passenger door shut, and replace the hood with a CF one.. If I were to make my Supra a dedicated track car I'd replace the fuel tank with a 10-gallon cell, and do as above. With as far as I've taken my Supra so far if I were to go to the track only step I could probably get my Supra down to 2800 lbsm if not less depending on how much stuff I want to re-design.
