Corner balance opinions needed
I just finished a suspension refresh (replating, Elephant bushings and trailing arm monoballs, etc.) and after a bunch of trial and error have arrived at the following setup:
LF RF LR RR height 24.9 25 24.5 24.5 weight 569 541 917 817 this gives: diagonals LF-RR 1386 48.7% RF-LR 1458 51.3% According to the LF/LR = RF/RR calc, the weights are off by 11 pounds. I had the diagonals closer but then the LF was about 70 pounds heavier than the RF, and I was getting the RF brake locking a bit ahead of the left (calipers, pads, rotors all working properly) and by equalizing the front weights a bit the locking went away. I found that the weights moved by 10-15 pounds just rolling on/off the scales, so I think the 11 pounds is likely irrelevant. BTW - car is more or less daily driver but is used hard at DE. All the adjustments were done with the sway bars removed. Opinions?

looks a bit off........and yes drop the sway bar mts so they have no effect.

Randy Blaylock and I had an enlightening discussion on proper targets for corner balancing....I began to rethink my settings and now tend toward targeting equal front weights, at the expense of having the "apportioned" weights off.....do a search.
Here it is.... * CORNER balanced - numbers from this...and the weight Wil

Yeah it was a good thread.
I posted my results, particularly the braking effect, to further the balanced front train of thought. In my case, I decided to compromise the diagonals and the LF/LR=RF/RR equation to sort the braking. Based on how the car felt at last week's track session, I think it is a good compromise. Thanks for input.
