The car still has full doors/windows minus the panels...
I have zero lexan in that car, that is a 150lbs I think total if I go lexan.
Then the dash is another 100lbs. Lightweight hood.
Lightweight wheels.

300 lbs+ easy. but it's $$$$
Then a lot of weight if I go tube chassis hybrid and aluminum floors like the Matt M's 8 second GTP.

Built engine + trans will open up possibilities power wise. The car can make 2000 whp with ease once built on both ends.
Now it's 4400lbs but 1150-1200 HP crank.
