On the original K, I trimmed the tube where the LCA mounts so I could move it forward. This gave me the ability to have 8.5+ degrees of caster and the tire is no where near contacting the back side of the wheel opening. This new K incorporates that adjustment and also moves the LCA mounting point up slightly. This will move the roll center along with allowing me to drop the car that same amount effectively lowering the CG also. So in layman's terms, I ran the LCAs perfectly parallel with the ground. If I would have lowered the car anymore, that would have angled them down toward the center of the car, along with the UCAs having a steeper angle down. This would put the roll center close to the ground and further away from the CG making the moment arm for roll much greater. Now I can lower the car while only making minor changes to the roll center all while lowering the CG. Thus putting the CG and roll center lower overall. This is my theory at least, which is as useful as a spare tire with no air in it.
