ATLANTA, GA (April 12) -- In the interests of safety, World of Outlaws Sprint Series Technical Director Martin Willis announced Monday that seat belt webbing coming into contact with any sharp or unradiused metal edge shall be protected from that edge by means of push on grip vinyl trim.
The areas of concern are the webbing slots in the metal racing seats. All seat manufacturers either roll the edge or supply the seat with trim protecting the webbing from abrasion or cutting under impact conditions. Webbing entry slots into the seat with an existing metal roll of 1/8-inch smooth radius will not require vinyl trim.
Where the webbing slot has been enlarged by filing or cutting is of particular concern. In most instances the edges have been left sharp, increasing the incidence of potential belt failure. As racing seat belts are subjected to severe conditions, it is encouraged that undamaged belts be replaced every 24 months. The date sewn onto the webbing should be used as a guide. Where the seat belt date is known to be "new old stock," it is acceptable practice to extend the replacement date on a set of belts to 36 months from date of manufacture. Damaged belts should be replaced immediately.
This is one area that the World of Outlaws would rather be proactive in their approach to their series. The regulations covering the newly formed World of Outlaws Late Model Series specifically cover the sharp edge issue. The belt replacement intervals are encouraged for the late models as well. The webbing protection from sharp edges will take immediate effect. In an effort to assist competitors in complying, vinyl trim courtesy of ButlerBuilt will be available from the World of Outlaws Sprint Series tech trailer for a limited period.
