In the event of a spin on track, the driver must either lock the brakes completely or
immediately depress the clutch pedal to avoid rotating the engine backwards. If the
engine rotates backwards it does so without proper oil pressure and damage can occur.

event the engine is operated outside these published guidelines, the Team is
responsible for all costs associated with the repair and rebuild of the engine.
