The ACR aerodynamic components are made from prepreg autoclaved
carbon fiber. Both woven and unidirectional materials are used.
The clear coated carbon fiber panels will have some variation and minor
waviness in the woven pattern. This is inherent to the process and a sign
of its authenticity.
All carbon fiber materials are susceptible to UV degradation during long
exposure to the sun. The ACR woven carbon components use the latest
technology for both the resin system and the clear coat. As with any
automotive coating, storing your vehicle in a covered location will guarantee
a long lasting finish.
The rear wing on the non two-tone ACR is molded completely with
unidirectional carbon fiber and painted in body color. Some patterned or
linear conditions may be visible in the painted carbon fiber surfaces. This
is also a normal result of the carbon fiber process.
