Weights
Car weighs 570 lbs on each of the front wheels, and 545 & 565 lbs on each of the rear wheels( no driver) this comes out to 1140 front / 1110 rear weights, or a 50.6/49.4 front to rear weight distribution on a total weight of 2250 lbs. The 10" aluminum front and 12 aluminum rear wheels and tires weighed 35 lbs and 40 lbs each respectively (150 lbs total). Add a driver to the car, and the F/R distribution will then become slightly tail heavy.

front
570570
without driver
545565
rear

Sprung weight is about 1800 lbs, and unsprung weight is about 460 lbs, for a ratio of about 3.9:1, which is fair, but not good.
