The Wisefab S550 Rear Kit completely redefines the rear suspension kinematics to deliver more mechanical grip, predictable behavior, and confidence at the limit. The optimized geometry keeps the tire planted under load, improves traction on throttle, and ensures smooth, controllable transitions. Built from high-strength materials and designed with weight in mind, the kit is both extremely durable and surprisingly lightweight, making it ready for serious abuse without compromising performance. Revised kinematics, not just dropped knuckle. If the focus is more towards performance, the car can act better with lowered ride height, but then the factory designed kinematics wouldn't work as its supposed to. This kit will give good kinematics with a lowered car - higher roll center with revised cambergain, anti-squat and bumpsteer. All for maximum grip. Easy camber adjustment. With double adjusters on the top links, camber can be adjusted easily at the track. Bump steer adjustment. Possibility to adjust bump steer by changing rod end location in a slot on the knuckle. Anti-squat adjustment. Possibility to adjust anti-squat by changing the front pivot length on the control arm. It can be done in less than 10 minutes at the trackside. Original wheelspeed sensor (ABS sensor) can be used. Works with OE brake callipers and rotors The wheel bearing can be either OE S550 or Mercedes-Benz (to suit Wisefab axles). Kit includes: Pre-set suspension links. Knuckles with hardware. Grip bracket for improved kinematics. Important notes: Hub to hub length (track) is the same as original, as this is defined by halfshaft lengths. Compatible with both separated spring and true coilover setups. Possibility to use with W Isefab axles (when MB wheel bearing is used) Recommended alignment specs: Camber: -0.5⁰ Toe: 3-10mm toe-in per side
