Thread: Just wondering....

Where A is the centerline of the strut...
B is a line drawn perpendicular to A....
C is the horizontal centerline of the lower control arm....
D is a line drawn from the intersection of A/B to the tire contact patch....
E is the centerline of the car left to right

Roll center can be changed by leaning the centerline of A to port or starboard. Leaning it inboard will raise the roll center and increase negative camber. Leaning it outboard will lower the roll center and decrease negative camber. It is said that lengthening or shortening the lower control arm will change the roll center also, but I fail to see how that would work without someone smarter than I am explaining it to me.

I can't put my hands on my copy of "Tune To Win" by Carroll Smith. It must be packed away in a box somewhere, but he could explain the relationship of the inner pivot points one to the other to prevent bumpsteer. This stuff is gettin' rusty on me....
