Adjustment shims

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2006 Audi TT, 2005 Audi TT, 2004 Audi TT, 2003 Audi TT, and 2002 Audi TT. However, it is still accessible from the selected car via links, so may be relevant.

Measure shims at several points using a micrometer. Varying tolerances make it possible to measure the required shim thickness exactly.
Inspect for burrs and signs of damage.
Install only shims that are in perfect condition.
