Upper half of the steering rack clamp to the frame.
Locates the rack laterally and vertically. Rack position directly sets bump steer, so mount accuracy matters.
No part-specific design process is documented. The Steering subsystem design process applies: 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.
