Another rookie post: The belts in the car I bought need to be replaced. I'm using the Defender HANS device and sometimes have trouble getting the 3 inch belts seated properly. There are several brands of belts that taper to 2 inches in the HANS area. Nesmith specifies "3 inch belts". Would these new belts not be allowed? They are rated the same. Also, Simpson belts are usually 75% higher than Crow, GForce and other comparable belts. Are Simpson belts really safer or just the paying for the name?
