Request for terminology definition

[tyoneal]

To All:

Could someone explain to me what, "Custom designed independent suspension to achieve a zero scrub radius with a low king pin angle", means?

This is a term I have not come across yet, and I am curious what exactly it means and what it does for the cars handling?

Here is some more context, and some questions within the statement that I added.
=======================================
ROAD STEEL CHASSIS DESIGNED FOR, "0", SCRUB FRONT SUSPENSION

BENEFITS:

*VERY SMOOTH COMFORTABLE FEEL OF THE FRONT TIRES

*DOES AWAY OF JARRING AND TWISTING FOR ON FRONT WHEELS (Does this mean that you can run really big front wheels and tires and it wont try and track the grooves in the street?)

*BETTER STABILITY ON STARAIGHT AWAYS

*LESS TIRE WEAR/CAN USE SOFTER COMPOUNDS

*TOUGHER DUE TO LESS LEVERAGE ON SUSPENSION COMPONENTS

*LONGER CONTROL ARMS EQUAL LESS ANGULAR CHANGE/LESS ROLL CENTER MOVEMENT

*COIL-OVER ASSEMBLY CLOSER TO L OF TIRE/GIVING BETTER SHOCK AND SPRING MOTIONS

*CONSISTENT ROLL CENTER LOCATION DUE TO LESS ANGULAR CHANGE

*LESS STEERING EFFORT

*LESS BENDING LOADS ON FRONT UPRIGHT ASSEMBLY

*TIRES ROTATE ABOUT THEIR OWN CENTER RATHER THAN BEING DRAGGED THROUGH AN ARC DEFINED BY SCRUB RADIUS

*STEERING IS MORE PRECISE

*LESS SCRUB ALLOWS SOFTER TIRE COMPOUNDS TO BE UTILIZED

====================================

Is this basically what the DSE and Speedtech front sub-frames do, or is this a totally different animal?

The terminology sounds like it is different, but I just really don't know.

I look forward to hearing all your comments and clarifications.

Best Regards,
