WM 4X00IN Specifications And Revision Intervals For Race Track Use - Vehicles With Central Wheel Lock: Information: Notes

The race track usage profile of many vehicles in the 911 model line now comes close to that of pure GT3 racing vehicles (e.g. GT3 Cup).

The component stresses associated with race track use and competitive driving are much higher than for a sporty driving style on public roads.

The following specifications and revision intervals for race track use must therefore be observed, particularly for highly stressed chassis components, in the same way as is required for GT3 racing vehicles.

The specifications for race track use described in the Driver's Manual are elaborated further by the following specifications and revision intervals for race track use. Findings from motor racing are incorporated into the usage specifications on an on-going basis.

Revision intervals for race track use are different for 911 GT3 (991) and 911 GTS/Turbo (991) vehicles.
