Opinions on these belts

I am thinking about buying these restraints and installing them in my rzr. Simpson is a brand that I trusted my life with back when I raced sprint cars and thought these would be perfect. If anyone with more information on weather these or an other brand would be better I am open to opinions. I am looking for a smooth installation process.Simpson Quarter Midget Latch & Link Restraint Systems 29025BK – Free Shipping on Orders Over $99 at Summit Racing
