The OMP Strada 3 harness features 2 inch wide lap and shoulder belts with a standard pushbutton buckle. The quick-release Y-style shoulder straps share one mounting point. All three mounting points are bolt-in and include 7/16" mounting bolts. The shoulder straps can be quickly unbuckled and put away when not needed. A great safety upgrade for your autocross car that still allows the use of the back seat during the week. OMP Strada 3 Harness is not FIA homologated or DOT approved.
