BTW weight in sig is with Driver.

how many times did I tell you it shouldn't be that heavy?

without real race weight in the car all is
but a guess
you weighed you're car but no fuel in
dep on gallon of cell used 8-12- 16-??
all that is weight mm and will thro off any curb weight you just listed
esp so if the car is a ladder bar or 4 bar
and dep on preload and such

with this being said
your car is close to that 3500-3600 at race
as for scales
it depend there to because some scales will 'break either on 25#
- 50 - or 100# breaks , yes, still be legal scales.
depend on over /under, if it closer to 15 break at the 25 mark
etc
i know of a challenger that weight around the 3000 # area
and could be easly be in the 2800#
that to depends on the scale its at
