My point is when you look at the thrust vector in the chassis its all wrong because of the instant center is well above the center of gravity of the car. This makes the car more sensitive to track conditions. As you pointed out more guys have problems with caltrac A bodies than any other suspension, thats the reason. The Chevy and Ford cars have 25+ inch long front spring segments (which puts the instant center in a far better location in the car) as opposed to the 20" Mopar, and thats why those car work well with Caltracs.
I'm looking at going back to SS type springs next year, I've had enough of the Caltrac KoolAid
