You may be reading that wrong It is not for 4 sets-Well actually it is but you need all 4 sets for 1 car-It is for one set of 20 lugs. 4 of them are locks-1 per wheel and the other 16 are regular. The silver pieces are the special lug sockets to fit the lugs and locks.It's for 4 sets, each including 4 regular lugs and 1 locking bolt. It works out to be about $31.25 CDN per set (not including tax or shipping) which is actually a fantastic price for racing lugs! It's a great idea for a group buy. Keep in mind, it appears to only come with 2 of those silver pieces (I can't remember what they're called!).
I think these ones are awesome! I doubt I'll find someone who wants to split the cost with me and I don't think I'd ever need all 4 sets myself!
