3/8" (10 mm)  AUTION: Replace rub strips when they are worn down to 3/8 in. (10 mm) on the front C 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. Adjustment Nut Lock Nut Splitter Cable Screws Length Adjustment 2.3 Track Extension 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).  AUTION: The track extension should only be used during closed circuit track events. The C track extension can cause premature damage to your vehicle if used on public roads.
