Any car that requires a rollbar must have a quick-release, 3-inch driver restraint system with a 2-inch crotch strap. The belts have to be clearly labeled as meeting SFI Spec 16.1 and be replaced every two years. If you have an aftermarket seat, the crotch strap must be threaded through it. If you have a stock seat, the strap can go around the front. We are going to anchor ours to the floor with a 3/8-inch bolt, nut, and washer once it comes in the mail.
