This is a 3" lap belt that I used with the stock seat belts for autocross. It makes a big difference with the stock seats. I would not recommend using it without the factory belts. I had to enlarge the holes in the belt tabs so they would piggy back onto the stock lap belt. If you're thinking of getting a cg-lock get this instead. It's a 3" belt unlike the factory 2" belts that the cg lock works with.
