T6.5.7 In any angular position, the top of the steering wheel must be no higher than the top-most surface of
the Front Hoop. See Figure 3.
T6.5.8 Steering systems using cables for actuation are not prohibited by T6.5.1 but additional documentation
must be submitted. The team must submit a failure modes and effects analysis report with design
details of the proposed system as part of the structural equivalency spreadsheet (SES) or structural
requirements certification form (SRCF). The report must outline the analysis that was done to show
the steering system will function properly, potential failure modes and the effects of each failure mode
and finally failure mitigation strategies used by the team. The organizing committee will review the
submission and advise the team if the design is approved. If not approved, a non-cable based steering
system must be used instead.
T6.5.9 The steering rack must be mechanically attached to the frame; if fasteners are used they must be
compliant with Rule T11.2.
T6.5.10 Joints between all components attaching the steering wheel to the steering rack must be mechanical
and be visible at Tech Inspection. Bonded joints without a mechanical backup are not permitted.
T6.6 Jacking Point
T6.6.1 A jacking point, which is capable of supporting the car’s weight and of engaging the organizers’
“quick jacks”, must be provided at the rear of the car.
T6.6.2 The jacking point is required to be:
a. Visible to a person standing 1 meter (3 feet) behind the car.
b. Painted orange.
c. Oriented horizontally and perpendicular to the centerline of the car
d. Made from round, 25 – 29 mm (1 – 1 1/8 inch) O.D. aluminum or steel tube
e. A minimum of 300 mm (12 inches) long
f. Exposed around the lower 180 degrees (180°) of its circumference over a minimum length of
280 mm (11 in)
g. The height of the tube is required to be such that:
i. There is a minimum of 75 mm (3 in) clearance from the bottom of the tube to the
ground measured at tech inspection.
ii. With the bottom of the tube 200 mm (7.9 in) above ground, the wheels do not touch the
ground when they are in full rebound.
h. Access from the rear of the tube must be unobstructed for at least 300mm of its length
Comment on Disabled Cars – The organizers and the Rules Committee remind teams that cars
disabled on course must be removed as quickly as possible. A variety of tools may be used to move
disabled cars including quick jacks, dollies of different types, tow ropes and occasionally even boards.
We expect cars to be strong enough to be easily moved without damage. Speed is important in
clearing the course and although the course crew exercises due care, parts of a vehicle can be
damaged during removal. The organizers are not responsible for damage that occurs when moving
disabled vehicles. Removal/recovery workers will jack, lift, carry or tow the car at whatever points
they find easiest to access. Accordingly, we advise teams to consider the strength and location of all
obvious jacking, lifting and towing points during the design process.
T6.7 Rollover Stability
T6.7.1 The track and center of gravity of the car must combine to provide adequate rollover stability
