Roll center. That's the only explaination for the short arms. As my friend Seaball said " the short arms are necessary to get the rc to sink, and the camberlinks obviously need to be even shorter for any type of gain when in bump movement.

if you remember our short arms/long arms thread, something i brought up was that there seemed to be a desirable amount of roll center drop/change regardless of chassis roll. and that cars that don't roll much, still need to produce a dropping roll center durring the movement. huh? was i on to something..."

Heyeva, I tend to think the car will run a softer spring. I really don't know though, since that would be based on the roll centers, the arm lengths, shock mounting, etc.
