pull all the electric motors out. The front seats has 6 motors in it??... like 70 lbs or something crazy?? plus ya got 2 in the doors, 2 in the headlights, 2 in the mirrors, and 1 in the power antenna? did i miss any??? who can do the math lol.. 13 motors @ average 7 lbs each plus the hardware. so call it 10 lbs each, for total of 130lbs in just electric motors crap..
then get the aluminum flywheel (-40lbs) and aluminum driveline or in CF(-40lbs). get the exhaust system made from CF or ceramic even.(-30lbs++). Get magnesium ultra light wheels w/ low pro tires(-100lbs). just start swapping or fabricate every thing else from carbon fiber... upper and lower controll arms front and back..there probly (-80lbs) both swaybars.(-20) on front and rear in CF and valve covers in CF(-5lbs), use the smaller lighter under drive the pullies(-10lbs). change the intercooler plumbing to aluminum pipe(-20lbs). Cf the glove box and dash and armrest console.(-10lbs) its a wash bit looks sweet.. drill the rotors out (-10lbs) and remove the spare tire. (-15lbs)
Pull the carpet and remove the pad and door panels.. (-12lbs).. weld all the spotwelds and seams and fill the frame with viagra foam.. stiffener it up a bit..(+5Lbs) pull the ac..(-50lbs+-) it would be cool to see a whole supra body in CF.unpainted... (-150lbs++) shhhwing..
these #'s are just tossed out there so dont quote me please as i have nothing to back it up with its just my guestimation and im probaly way off.. and its late lol...
however, that may trim 600 -700 lbs of dead weight maybe bring it down to under 3000lbs or less.? just need to preload the rear end a bit with torsion bars? and or sandbags now to get some good hook up.. besides replacing floors and crap with aluminum or CF.. i think thats bout it..? replace glass with lexan?? any thing i didnt address? fill tires up with heliumm lol ok ok now thats just plain silly. hmmm...
my 2-6 cents..
h34r: less weight = fast and loose..
