I made a set 35 years ago with four very mechanical scales obtained from a meat packing house for pretty cheap. Digital stuff wasn't invented yet. Had them calibrated and certified by some guy from the City on a regular basis. It was pretty accurate on single seat race cars, but you could still scratch your nose and make all four start clattering. Generally had things dialed down to 6-8 lbs at the front, maybe a max of 20 lbs at the rear.

How do you corner balance a 911 with any accuracy? If you get it dialed with just you & a half tank of gas, what happens when you pick up a sack of fertilizer at Home Depot w/ the wifey and then make a panic stop of the Harbor Freeway?

Trick question. You must put the fertilizer on your lap to cancel out the wife. Hope she is a petite little thing!
