PURE DRIVING PLEASURE.
BUT SAFE.
WE TEST FOR YOUR SAFETY.
VOLKSWAGEN ACCESSORIES.
BECAUSE QUALITY IS ALWAYS WORTHWHILE.
A good grip, reliable acceleration, controlled driving dynamics – hardly any components bear so much
responsibility as the wheels. Both for safe driving and for the complete look of the vehicle. Our develo-
pers, designers and engineers master the balancing act between form and function on a daily basis. They
do this by unifying top-quality materials with first-class designs to corresponding functioning. And by
testing the results for so long and so intensively until they meet our Volkswagen demands on quality and
safety.

We are not satisfied with offering you high quality standards. Therefore our inspection procedures are
more extensive, stricter and harder than is demanded by law. And our products are simply safer.
Strength Tests:
The rotating bending test simulates the load on rims when travelling through bends, whereas the roll-off
test checks the wheel under overload conditions and in the impact test the impact strength of the edge of
the rim is tested.
Material & Surface Tests: In these tests both the chemical composition, tensile strength and elongation
values of the rim and the resistance of the surface to scratching and corrosion are derived.
Endurance Testing: The endurance test takes place using a bi-axial wheel test bay (ZWARP).
Here the greatest loads which can occur across the lifetime of a wheel are simulated.
Vehicle Tests: In the clearance test, the wheel bolt tightness test and the threshold test the wheels are
tested under hard conditions on the test track.
