SECTION 5: STEERING 5.1 Steering Modification Requirements 5.2 Heat Treatment and Chrome Plating 5.3 Steering Rack Shortening 5.4 Manufactured Steering Linkages 5.5 Checking the Tracking of all Four Wheels 5.6 Steering Columns 5.7 Steering Universal Joints and Couplings 5.8 Locking of Steering Components 5.9 Steering Wheels 5.10 Steering Position 5.11 Illustrations/Diagrams 5.1 STEERING MODIFICATION REQUIREMENTS 5.1.1 Steering boxes and components from various donor vehicles may be used. The steering components must be of adequate strength for the intended Street Rod and the steering ratio must be suitable to permit safe manoeuvring and Street Rod control. The steering box ratio and steering arm length must be compatible so that excessive force is not required to operate the steering. 5.1.2 Steering components must all be compatible. This should be achieved by selecting a single donor vehicle. A clear record should be kept of the make, model, year and identifier to enable parts to be sourced in the future. Note: Steering components should not be lightened; the donor vehicle should be of at least the same size and mass as the Street Rod under construction 5.1.3 At least 10mm clearance must be maintained around all steering components throughout the operational range of the steering and suspension. 5.1.4 Lock stops must be fitted to prevent over-lock and maintain steering component clearances if they are not integral to the rack or steering box design. These may be fixed or adjustable and locked. 5.1.5 Fabric steering joints shall be heat shielded if less than 50mm from the exhaust 5.1.6 The street rod must be able to turn in a circle not over 25 metres in diameter, measured by the outer edge of the tyre track at ground level, whether it turns to the left or to the right. 5.1.7 Examiners may require an engineer’s report if is any concern about any aspect of the design, strength, integrity operation of the steering. 5.2 HEAT TREATMENT AND CHROME PLATING 5.2.1 It is critically important that the strength and fatigue resistance of all steering components is maintained, therefore forged or cast steering components must not be reworked by welding or heating unless the component has subsequently been appropriately treated and approved in accordance with Appendix C to Section LZ of VSB 14. 5.2.2 Due to the risk of hydrogen embrittlement, stub and other critical steering components must not be chrome plated.
