Our Chassis weighed 51 lbs(23 kg) when it came off the Jig table.

Our projected weight after tabs and powder coating is around 54 lbs (24.5 kg).

I hope this helps.

These frame numbers are great, but what kind of rigidity numbers are with them? Just curious...

[Kevin Hall]

Well, the one we just punched out weighs 53 lbs, and has a rigidity of 1300 ft-lbs/deg. It is an all 1" tube frame.

Our next design incorporates some composites, and is running about 60 lbs, however the rigidity is upwards of 2100 ft-lbs/deg.

Charlie,

Was the rigidity tested with a fully assembled car or just the frame?
