Blaine and I had a brief conversation the other day about COG guesses. Since then I have played around with the 4-link calculator and remebered/realised a few things...
The front to rear location of you COG is irrelevent in regards to calculating your antisquat. It's height above or below your instant center that controls AS%.
Blaine suggested that my COG might be 6" lower than I had guessed (I used the top bolt of my bellhousing). That 6" drop in COG changed my AS% from 70% to 86%... pretty substantial.
So yes, knowing the exact location of your COG is extremely important if you want to design handling characteristics into yoiu suspension.
