I just drove through a local certified truck scale and the car's weight was 3,580 lbs.
That is with roughly half a tank of fuel and I weigh about 140 lbs. myself

I figure that the car is about 3,440 lbs. with fluids, half a tank of gas (11 gallons of 22 gallon fuel cell),gutted interior,race seats, full cage, fiberglass hood/ trunk/ lower front valence, etc.

since a gallon is about 8.34 lbs., 11 more gallons for a full fuel cell would add another 92 lbs. bringing the curb weight to approx. 3,532 lbs.

No idea on front/rear weight bias though?

I have not taken the door beams yet and I have a cast iron 340 up front. Still lots of work needed to further reduce weight

No wonder my gas mileage sucks
