Ok guys , I have watched this for long enough. It is true that his fender does not have 1" in of vertical material even in stock form. Due to the design of this fender with its compound angles, it provides a very substantial platform even without the said one inch of material. This fender IS ARMA legal, as long as there are not DRASTIC modifications. Anytime when working with metal, sharp edges need to be addressed (those remaining from flaring, cutting etc.) as they present a definite safety issue. The intent of the one inch material rule was put in place not to hinder drivers' creativity but to ensure driver safety and reliability in the event of a crash. Anyone who does not believe that this rule was put in there for this reason needs to re-evaluate their questioning of the rule. If anyone has any questions concerning this post feel free to contact me directly.
