I bought 8x 400lb scales at Target today for $20ea. I was concerned about my corner weights after the crash at VIR and the work by a frame shop to straighten out my right front. It looked to me like from RF was about 1/2" higher than it should be. Turns out my corner weights are ok.
Get 400lb scales and put 2 at each corner. Put a short 2x10 across each pair of scales and then lower the tires on to the boards.
