AM3 contains suspension points that are excluded from the average:
aa12,aa13,aa14,bb12,bb13,bb14
Exclusions usually occur if suspension points are part of the stabilo but not attached to a dedicated stabilo
main line. In other cases they might be excluded due to their function as stabilizer in case of a large front collapse.
