Shields the driver from the steering rack.
A rules-driven shield preventing driver contact with the rack in a crash, and part of the no-snag-point assessment. Design Philosophies and Processes: Inherited from the Steering subsystem design process: 1. Kinematics sets steering geometry, Ackermann targets and rack travel. 2. Size the column and shafts for torsional stiffness and for the bearing housing that supports them. 3. Calculate static steering force from the tire and geometry, and check it against anthropometric limits. 4. Design the wheel shell around the button and switch layout and the dash sightline; prototype grips and take driver feedback. 5. Validate steering effort and Ackermann on track, using the alternate tie rod mounts to sweep setups.

Fault Vault, CR25, Design, Complete Failure. The design did not consider that the steering rack cover would need to extend all the way to the side to cover the new internal damper package. Another rack cover was laid up, cut up and bonded to the original to extend the coverage.
Coverage extended to the side to cover the internal damper package; a second cover was laid up, cut and bonded to the original as the interim fix.
