(often referred to as Lotus Suspension Analysis or LSA ) is a professional-grade simulation tool designed by Lotus Engineering for designing and analyzing vehicle suspension and steering geometry. It is widely used by automotive engineers, students in Formula SAE (FSAE), and BAJA competitions to optimize vehicle dynamics.
: It calculates critical derivatives such as Camber Angle , Castor Angle , Toe , and Kingpin Angle .
: The most critical part of the process is reviewing graphs, such as Camber vs. Bump, to ensure the tires maintain maximum contact with the road throughout the suspension's range of motion.
: The software includes pre-filled templates for standard suspension types, including Double Wishbones , MacPherson Struts , and Push-rod/Pull-rod systems.
