In case anyone hasn't read this one (link attached), it is very enlightening and entertaining. My ride heights are uneven, and my weights are very close to 500/500/800/800. I don't have 10 pounds of difference anywhere F-F, R-R, or diagonal. I have to get mine done again due to tire, wheel and Elephant Racing bushings, and I'll spend the couple of hundred to do it.
* CORNER balanced - numbers from this...and the weight
