    Might consider a modern light weight battery and leave it up front. Saves you the weight of a long length of heavy gauge battery cable and a shut off switch plus the weight savings of the lighter battery. When our only choice was heavy batteries it made more sense to move them to the trunk, especially for drag oriented cars.

    Now that I've finished adding the roll bar, harnesses, seats, and trunk-mounted battery, I'm planning on putting the interior back together. However, would it be ill-advised to put the carpet back in without any sound/heat insulation? I drove the car around and don't mind the added sound and heat.

    In drag racing for every 200lbs lost , that's worth a 1/10 sec reduction in ET

    Our car's interiors can't weigh all that much....it's mostly plastic panels and a few screws.

    That's exactly what I was thinking. I've only removed the seats, some panels, and the carpet, and none of those really weigh a lot.

    Question is, would it be okay to lay the carpet down without anything between it and the floorboard? I'm just thinking it may be a potential fire hazard without any sound/heat insulation beneath it.

    I'm "thinking" there's a member here that sells a light weight floor insulation.

    You could also look at using an "aluminized heat barrier" sheeting like the stuff from Cool IT/Thermo Tec. Adhesive backing that can be used on the outside floor boards where the pipes and mufflers are. I used it, (#13590) works great to keep the heat away. Also, the little weight you add from the carpet underlay is in the "middle" anyway.

    If you install a roll bar to increase safety after removing the door crash bars.... You will not have saved weight and the roll bar is still in the middle of the car.

    At this point, I am not exactly trying to save weight with the interior, as I've already decided on keeping the interior. My question is do I NEED insulation between the floorboard and the carpet? I don't mind the added sound and heat, and I'd rather not buy and go through the process of installing it.
