I loaded the seat with weights from my weight bench (finally found a use for them) and like Sean my racecar was over 1700.  Don't have the numbers here to look at the individual corner weights.  Ex C-Sedan built in the 60s, full cage back then was less than today.  Came with a big lead weight mounted on the right rear floor, stock gas tanks and battery.  In the late 70s it was eligible to run GT-4 with cage upgrades and a fuel cell, so I added the cell and some door bars and footwell protection to meet GT rules, but never went to big wheels and brakes, stayed with 10s, ran a few times as GT-4, then GT-5.  Stopped racing for 20 years, then dusted off the car and brought it back and ran once or twice as GT-Lite, then vintage car and that is when I weighed it. The cage upgrades had put weight where I didn't want it, I remember left side heavy, nose heavy. 

Sean , Thanks for the info. Much appreciated. Jim

Our endurance racing Wolseley Hornet weighs in at 1522 without driver. Full cage, 12 gallon fuel cell in the boot, regular battery, fire system, BMW Twin cam A-series, 10' wheels. I should weigh a street car one of these days and see how it compares

LF 453 lbs RF 458 lbs

LR 305 lbs RR 306 lbs

60/40 split front/rear

Does anyone know the weight of the mini with corner scales? Obvious there is a big front and rear weight difference.
