The last item on my list to get my SPEC 944 ready for a test day was to corner balance it.
Ideally, I should have done this before I got my alignment, but the timing didn't work out. And I knew the car would be close to balanced as it was sitting level at 4 3/4 inches at all four corners as measured from the rockers.
So, having borrowed some scales from 944 SPEC director locally, I set them up in my garage and got to work. The number I was really concerned about was my cross-weight.
Now, I won't explain, but you can find out all about corner balancing here.
Right from the get go, my cross-weight was 49.81%. Which is about perfect.
But wait, I didn't check how level my garage floor was. Checking, it was 2 inches lower in the back than the front. Oops. After leveling the scales my cross weight was 48.1%. Not good enough.
So, with some minor,(less than a quarter turn of my coil overs) on both front corners I was able to get the cross-weight to 49.51%. Ahh, good enough.
The above chart is courtesy of here. My numbers are on the left. I was not about to try and get to their perfect numbers as it is a bit of waste of time. I mean fuel load, tire wear all effect the corner balancing.
But, I am in the sweet spot and can't wait to get out on track.
