Thanks for the link Dave. When we were racing go-karts, I bought 4 bathroom scales and set the car up before each race, depending on the track, with driver in the seat, helmet and all equipment on, tires aired properly and fuel in the tank, ready to race. It worked really well and we went around the track like the car was on rails.

I've often thought that the same thing could be accomplished with a full-sized vehicle and bathroom scales. Most of them are 250 lb. capacity, so you would need maybe 3 or 4 of them, depending on the car weight on each corner. Line them up side by side and use a 4x4 piece of lumber the length of all the scales (3 to 4 ft. long). Position the scales so that the center of them left to right will be under your weighing point. This could be done with tires and wheels on the vehicle so long as you raised the other 3 tires and wheels to the height of the corner being weighed. Air the tires to the pressure you want all around first. Lay the 4x4 on the scales and let the corner down with the tire resting on the 4x4 and add up the total of weight on all the scales. Deduct the weight of the 4x4 and you have that corner weight. Move to the other 3 corners and repeat.

If weighing without tires and wheels, just position the scales in the center of the point where you're going to weigh, lay the 4x4 on the scales and use other pieces of lumber to build up to your weighing point. Deduct the weight of the lumber used and you have it.

I've seen scales for $20 to $25 at WalMart and other large discount stores. Ebay may have some also.

What do you think?
