Perfect for autocrossers or track junkies that don't want the hassle of installing competition belts in the car. Easier to use than any other product on the market, Modifry's Seat Belt Lock (SBL) allows you to lock both the lap and shoulder belts with the flip of a switch. 

Want to "be one with the car"? Just flip the switch, push yourself back in the seat, and feed the belt slack into the seat belt reel. As you feed in the slack it locks and will NOT come back out. The more slack you feed in the tighter the belt gets. Once you're in, you're in. No more sloshing around in the seat!  Because it locks both the lap and shoulder straps it's much more effective than mechanical belt locks that only tighten the lap belt. And you can leave it in the car all the time and turn it on at a moment's notice!
