The RACE 6 HANS SFI is the same as the RACE 6 but with 3" to 2" shoulder belts that are compatible with the HANS device and other head and neck restraints. The lower section of the shoulder belt, including the adjuster, is 3" while the upper section of the shoulder belt, where it passes over the head and neck restraint, is 2" fitting perfectly on the friction surface of your HANS device. Standard 3" shoulder belts will work with HANS, but the 2"/3" belts give you a better fit and allow you to optimize the installation angles behind the seat. There is no difference in either the strength or elongation of the 2" webbing compared to the 3" webbing. The SFI 16.1 standard provides for 2" webbing on the upper shoulder belt to be used with a head and neck restraint. You should check with your sanctioning organization to see if they have any rules or regulations that may require 3" shoulder belts. Available in black or green.
