Although the mix of materials in the racing car is more complex, Audi has integrated manufacture of production and racing cars even more closely with the second generation of the R8. In the Böllinger Höfe production facility, Audi Sport GmbH manufactures the chassis of both variants together. Though the racing car receives, for example, adapted aluminium cast nodes and a steel roll cage. For the assembly of such motorsport components, the racing chassis is removed from the production line and then reintroduced again. Nevertheless, the racing chassis of the R8 LMS remains integrated into basic production process up to the construction of the roof and the cathodic dip coating (KTL), which is a kind of primer. Then the racing cars are completed in Heilbronn-Biberach.
