At ls1.com.au we have a "quick list" where users can have their 1/4mile times added and we have it in 10/11/12/13 second brackets and the cut off is a 13.9 to be on the list. Also has list of basic mods(heads/cam, supercharged/nos, slicks, diff ratio, weight) etc. Recently we've added what state as well for some friendly rivalry
just a suggestion
