S2000 Corner Weights
I was just up at Roebling Road in Savannah, GA and used their scale to measure corner weights for my car. The car is stock with the tool kit removed, but not the spare tire and a nearly full tank of gas. The other items that may matter include a Da'Lan hitch mounted on the back, a Sparco Roadster seat mounted in the driver position, and two small amps in the area above the gas tank.
Car only, total weight 2830 lbs:
699 685
734 712
Me sitting in the car, total weight 3013 lbs:
739 707
812 758

Wow. CoralDoc you beat me to it! I, too was at Roebling this weekend and weighed my S2000.
My car had about 1/2 tank of fuel, and was completely empty. No spare, tools or driver.
LF 710 RF 660
LR 674 RR 683
Total weight - 2727 lbs
Although the Front Rear measurments indicate roughly a 50/50 balance, I was a bit surprised by the variation in the front wheels. 50 lbs seems to be a pretty big variance side to side.

The swaybars are almost guaranteed to be applying some kind of load on the suspension, and this is going to throw off the corner weights. This is going to be true even if the car is perfectly leveled. This is because the swaybars are not likely to be perfectly straight and also because even if they were, variations in load distribution (actual corner weights) are going to vary the ride height at each corner and thus, cause the swaybars to come into effect.
Its hard to say exactly how much of an effect this is all going to have though... could be not that much, or it could be a significant amount. Its a whole other variable that affects, and is affected by, all the other variables.
So if you're trying to accurately corner weight a car, you *must* unhook the swaybars. Then, if you're really hardcore
, once you get the car on a level surface, you use your adjustable endlinks to zero the preload from the swaybars.
Now, the total weight you get from those scales are still going to be valid, as are the front and rear totals. It should just be the left to right (and therefore also the cross) values that lose their accuracy.

It seems to me that the sway bars will have no affect on the accuracy of the scales. You can have any kind of crazy load transfer mechanism you want on the suspension, but when at rest the scales will tell you exactly how much weight is on each wheel.
