My steel framed 1990 GTD corner weights as follows: RF = 620 lbs. LF = 610 lbs.
RR = 750 lbs. LR = 775 lbs.
Thats with each side tank half full and 180lbs. in the drivers seat (LF).
Thats a 45% front and 55% rear with a total of 2755 lbs. including driver and fuel or 2491 lbs. without driver and fuel. This car is fully upholstered, has A/C galvinized and painted frame, a lowered floor pan, added rear engine bay fans, light weight odessey battery, stainless steel floor pan and wheel housing gladding, Renault transaxle, 15 inch ally wheels, modified 65 289 with iron heads and ally intake and a plastic rear outside window. That should give you enough detail to work things out.
