We found that on our FSAE car, the suspension geometry affects handling pretty much like you are describing Marc. By having the roll center closer to the center of gravity we could reduce spring rates and have a much more controllable car. By letting the dampers do their job - which is to dampen uneven track (up and down), and not compensate for body roll. Let the suspension arms take the lateral forces.

As you are saying Marc, and you Caddy briefly mention, when lowering a saph the control arms make the roll center go below ground and adds massive body roll which then needs to be compensated for with stiff ARBs and high spring rates.

This is the first time Ive seen the actual figures for the "stock suspension" Sapphire, so massive creds to you for taking the time Marc.


A WRC tarmac setup will pretty much do what you want.
