is that stuff really gonna make a difference? floor mats, change and useless crap in the glovebox? it might get rid of 3-5 lbs tops. i didnt sweat the small stuff when i went. i even had my CD case and camera in there. im not discouraging removing every little pond tho, but for the weekend racer or once a month racer, i would just focus on the big ones like pass. seat, rear seat, spare tire/jack, and MAYBE front sway bar
