Really interesting information. My car is 45/55 distribution. When I was designing the brakes, I had to guess at the CG height. I guessed at 17". Seems I probably was not that far off.
Being the educated one

let me ask you something, is the ERA front steer? Either way, how do you dial in more ackerman?
Here is another, for a bias ply tire of OEM sizes (245/60, 275/60), what are good camber curves?
One more. Does your ERA have a Jag rear end and did you determine the roll center height?
Thanks
Rick
