OMP EB0-0578 two-inch motorsport tow strap approved to FIA Appendix J Article 253

If the Tow Strap Rips Off, It Wasn’t a Tow Point

A tow strap bolted to thin sheet metal is decoration. FIA rules make the real requirement obvious: recovery points need structure, access, visibility and a load path that works.
