Corner balance, any tips? Options

[tradisrad]

I am going to corner blance my 914 in the next week or so and I am looking for any tips that my help.

I picked up a set of Mad Racing scales, a Longacre caster/camber gauge and toe plates off of CL for $200. After I purchased said items I could not find a lot of info on the Mad Racing scales:



I did find that folks don't like these scales especially when compared to the Longacre digital scales. It also seems that there is a question about repeatability and accuracy with this type of scale. But they are what I have.

So, I would appreciate any advice on using these scales as well as the camber/caster gauge & toe plates.

My suspension set up is:
Elephant Poly Bronze x 4
GPR front bar
Stock torsion
Upper front monoballs
150lb Eibach springs w/ ground control
Bilstein shocks x 4
Turbo tie rods & bump steer.

The tires and wheels need to "float" or you have to roll the vehicle after each time it is jacked up. It makes a SIGNIFICANT difference. Note the red device on top of the scales when I corner balanced my car. They are ball bearing plates. With 2 fingers I could push my car around on top of the scales. You can also use grease between 2 pieces of sheet metal under the tire but you risk losing the car off the scales and hurting yourself if not restrained and they don't work as good as the ball bearing plates.
