Tried to open & all it did was shutdown my computer. One thing you should have is a sternum strap. It mounts higher & can keep from straining you breast plate whethe ribs join. NEVER CROSS YOUR BELTS IN BACK, connecting spots should be as close as possible to you & the seat, do not use too much padding in the seat, keep belts tight if they're loosening too much in a race get rid of them you don't wanna get beat to death between the belts & the seat, & belts get a lot of exposure on open trailers. I've had arguments w/ anengineer on this but think about it. You're going down the highway60 - 70 (ok whatever) the belts are exposed to sun, dirt, wind all the junk. they wear out faster. Look at the webbing in your belts, is it straight? Looked at a set w/ Rick Nichols after a hard crash & the webbing was pulled & cooked. They've served their purpose, cut'em up &throw them away. Just a few ideas gang, want to see all race as long as possible. stay safe
