Ride and Roll

Sacli suspension systems control the ride rate with dive suspension wheel rate while they control the roll rate as a combination of dive and roll suspension roll rates.  As a result Sacli suspension allows for high wheel hop frequency with less compromise on the compliance of the system compared to a conventional suspension system.  High wheel hop frequency allows the wheel to grip better over small, high speed road irregularities by letting it follow the road easier.  The compliance of the suspension minimizes the disturbance in weight distribution over bigger and slower road irregularities.

Sacli suspension doesn’t lose camber with body roll and can be allowed to roll more as a result of this advantage.  It’ll have a set up with more roll compliance. Roll compliance would slow/reduce weight transfer during transient state cornering, improving overall grip.
