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.

I used a similar "fulcrum-based" lever system on my old MR2 CSP autocross car with good results. I'd echo what Andy says and agree with JJackson that it is an iterative process.

One thing to keep in mind is that you need as close to a perfectly flat measuring area to get good results. I started by parking the car in the center of my garage (to allow for lots of space around it to work on things), and marking 1-foot squares for each tire contact patch. I then used clear tubing & water to check the flatness of the four contact patches; I used 1/8" vinyl floor tiles to prop up the low spots in my garage. I then went back and painted the squares onto the floor using a vinyl tile and spray paint. Then I built ramps out of 2x8 wood so that I could drive onto the lever pads after making each change to ride height and alignment (you'll end up doing this repeatedly, since a change in ride height changes alignment and vice versa).

I plan to use the same system for my teener when it is done (someday!).
