Individual wheel weight scales.

I did that too. I had access to an industrial beam scale that could weigh up to 1000 lbs, so I built three platforms the same height as the scale for the other three wheels.
Trouble is, I don't have access to the scale any more, the company I worked for folded, and I retired.

I’ve used several different brands. Intercom and Longacre. I forget the other one.

The biggest difference was the one I can’t remember was the older of the three, and you had to write down the numbers. The other two had printers IIRC. Haven’t used corner scales since 2007.

They are worth every penny. One thing you can do to offset the cost is scale local cars. The issue is going to be teaching the value in corner scaling. You’ve already seen the posts saying use truck scales, which are inaccurate at car weights and you can corner scale with them.
