A few more areas to perform a little 'lipo' on the 2.
Frunk hood, 32 lbs
Trunk hood, 15 lbs
Engine cover, 13 lbs
Front bumper, 30 lbs
Rear bumper, 32 lbs
That totals 122lbs. With some creative work we may be able to lose 40 to 50 lbs here. There's a lot of metal that won't be necessary for the track. The hoods have the support structure that is designed to keep sheetmetal straight for an extended period. Unnecessary here, cut it all out. The front hood can lose a little on the top, I'll use 'glass the diredct the air up and out. Replace the foam in the bumpers with lighter 2 lbcuft foam and cut the steel a bit. Only really need the structure hold the general shape of the bumper. Also planning on replacing a lot of metal and plastic mouldings with foam.
