they have lug sets at pep boys and whatnot for like 20 bucks or so, i don't know where you got 100, there are also sets that are all locks, if your worried about losing the wheels, and if your reallly concerned, get 5 seperate lock sets and put 1 on each wheel, i bought my locks at the autozone or whatever on 60 where its in that strip mall with the UPS store
