corner balance question

[Howard Nelson]

I am in the middle of corner balancing my car, and have been able to get the diagonal weights very close. I don't think it is possible to shift weight from side to side (or front to back) just by adjusting ride height (including me, my driver's side is ~130 lbs heavier) - so my question is: Is it better to have the side to side weight ratios equal for both front and rear, or, is it better have the front weights equal (since the front produces most of the braking?) What are your thoughts? Thanks.

I'm not much help but see if your answer is in this thread.

Corner weight/height questions

[Howard Nelson]

Thanks, autobonrun. I'm not sure about Chuck Moreland's statement in the other thread that "When corner balancing your goal is to get the F/R ratio the same left and right. That is LF/LR = RF/RR." I would argue that the side-to-side balance is more important since braking and steering occur along these axis. In other words, LF/RF = LR/RR. If each side weighs the same, Chuck's statement also is true, but since my car is heavier on the left side (with no passenger) the question in my first post came to mind. And no, I don't think it is possible to shift the weight from the right side by raising or lowering that side - the four-legged stool is a really good example.

In a perfect world the sides would weigh the same. But the world isn't perfect and our 911s are not symmetric.

By achieving LF/LR = RF/RR you create even handling in turns. The percentage of weight loading on each tire will be equal front to rear for both left and right turns.

You also achieve equal ride height left to right with this configuration, anything else and your sides won't be (can't be)equal.

Braking is also best with the LF/LR = RF/RR configuration. It is true that if LF=RF you could optimize front braking force, but it would be at the expense of the rear. Your LR and RR would be way off and you would experience premature lockup on one of your rear tires.

Guys;
You lost me. I believe that the objective is to get the diagonals equal, so that would be to get LF+RR = RF + LR. Unless the car is a purpose built race car or ballested, you will never be able to get the left side equal to the right side.

Or did I miss something...?
