After finishing a session of high-performance driving on the race circuit, “cool-down laps” must be driven in order to reduce the temperature level of the assemblies that are subjected to particularly high thermal loads (brake system, engine) in a controlled manner. Stopping the vehicle immediately would result in a further increase in component temperatures due to the resultant stationary heating process. In extreme cases, this could cause irreparable damage to individual components.
Certain motor sports equipment may not be legal on public roads, such as six-point seat belts, emergency-off switches or door struts and A-pillar struts on the roll cage. The same applies for the modifications to the chassis and aerodynamic com-
The purpose of the following vehicle checks is to ensure the proper condition and operational reliability of the vehicle for high-performance driving on a race circuit. Due to the particular stress and strain on the vehicle during high-performance driving on the race circuit, a number of additional aspects must also be taken into consideration. These are summarized for the most important assemblies.
Engine oil An oil level of 3 segments above the minimum marking is recommended for optimal engine operation, also for high-performance driving on the race circuit. When adding engine oil, always keep in mind that the quantity difference between the minimum and maximum markings is approximately 0.8 quarts (0.8 liters). Never overfill with engine oil. In addition to the regular oil level check, the engine oil and oil filter must be changed after 6,000 miles ( 10,000 km) of high-performance driving on the race circuit.
00_01_14 A = Quantity difference of approximately 0.8 quarts (0.8 liters).
