Dodge 2008 Viper Supplement - Manual (Page 7)

3/8” (10 mm)
CAUTION: Replace rub strips when they are worn down to 3/8 in. (10 mm) on the front
edge. This will avoid damage to the carbon fiber panel.
Regularly inspect the outboard knock-in threaded insert to avoid premature splitter wear
(right and left side). Replace these fasteners as needed in order to protect the carbon
fiber splitter panel.
A splitter track extension is included in the trunk of every Viper ACR. The track extension
is mounted in the same location as the center rub strip. The on-track aerodynamic
balance was optimized with the track extension in place.
To install the track extension, remove the eight (8) screws of the center rub strip and
install the extension in the same mounting locations.
Tighten fasteners to 70 in-lbs (7.9 N·m).
CAUTION: The track extension should only be used during closed circuit track events. The
track extension can cause premature damage to your vehicle if used on public roads.
