Timed life components

In order to avoid fatigue failures, certain parts on your car should be replaced on mileage / time intervals listed below. These intervals assume a safety margin with typical racing use and do not account for crash damage or other lifespan-reducing circumstances. If a crash or other lifespan-reducing incident occurs, you should consider replacing those components earlier.

You should regularly crack test these and other components involved in any incidents which may reduce lifespan.
