NC Cams Is right bathroom scales work really well. I have been set for over fifteen years. They will get you too within 1% if you’re careful and do your setup exactly the same. I’ve checked the results with my Longacre's scales. Will they tell you if your car weighs say 2350lbs exactly, no but they will tell you your cross weights or rear bite to within 1%. I still use the bathroom scales when we go out of town and race because if they get stolen I would only to lose 150 bucks. The hydraulic scales that used to be made I believe were made by Rebcco if memory serves me right. They had a bad problem with binding from the side loads that the chassis put on the scales. I think you’re designed would have problems with binding from suspension movement and Camber. Your tires have to float on the scales to get accurate reading. Even Longacre's scales will give you a false reading if the tires don’t “float” and let the suspension settles naturally. Or you could look at it this way buy 4 electronic bathroom scales and you’ll be 21st century dude.
