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've got elephant poly bronze on all 4 corners and there is no binding. the lever arms roll out from under the car when loaded & the car can rock back and forth on the balance plates; I also bounced on all 4 corners in a effort to settle the car. My results seem repeatable.

the problem I am finding is that with me in the car I can't balance it with my low spring rates.
w/o me in the car my weights were:
lf=496 rf=480
lr=568 rr=560
total 2104
I am sure I can dial this to be perfect and shift more weight up front, but it was not the goal.

put me in the car and the weights change:
lf=556 rf=508
lr=644 rr=572
total 2280

in order to lighten the left side of the car I found that lowering the left rear yielded the best results and I got minor results from lowering the right front. With this I still had a 50lb difference side to side on front and rear with the weight being on the driver side. The car sat like a lame duck (sorry no pics, it was embarrassing) with the left rear being some two inches lower than the right.

I believe the inability to shift the weight w/o having a jacked up stance is due to the low spring rates. I think if I had 300# springs I'd be able to balance, but they would kill my hemorrhoids.

Hence I think it may be in my best interest to balance the car w/o me in it. It will look/sit decent and may exhibit a minor improvement in handling (like I would really notice!).

If it is possible to balance my car with my current springs & t-bars and not have it sit totally crooked please help me!
