Short-long arm (SLA) suspension is a double-wishbone design where the upper control arm is shorter than the lower one. This geometry induces negative camber as the suspension compresses, keeping the tire patch flat on the road during heavy cornering. It is highly valued in performance cars and light trucks for its superior handling characteristics and predictable camber gain.
We need to check the ball joints on that SLA setup before doing the alignment.
