Hints: From the Competition Car Suspension book.
Short SAL (500 - 1000mm) gives very good roll centre location, keeps the outer wheel vertical in corners, but going badly to positive camber in droop and negative in bump (accelaration squat and braking).
Long SAL (1800 - 4500mm) provides lower roll centres but less control over their sideways movement, minimal scrub (track variation), poor outer wheel control going into positive camber, but only small camber change in bump/droop.
Medium SAL (1000 - 1800mm) is the transition area between long and short with, as you might expect, a bit of this and a bit of that.
Ultra-long SAL (near parallel) provides excellent vertical control of very low roll centres but possible enormous sideways movement, wheel angles virtually unaltered in bump/droop but very poor control of wheels in roll, with near equivalency to body roll angle.
