Dynamic toe adjustability via bump-steer adjustment

you can benefit from optional "C6 Rack Offset Spacer Kit" that will allow you to achieve even bigger steering angle on C6 chassis (not needed on C5) and improves the Ackermann curve

but then the factory designed kinematics won’t work as they are supposed to

You can also upgrade your pre 2021 Wisefab S13 rear suspension kit to new toe arm design by purchasing "S13 Rear Suspension Mod Kit"

Feal Suspension strongly believe that the 441 coilovers have an edge on shock design that gives you confidence and a competitive advantage where needed most
