What kind of lug nuts do people use? My lug nuts are starting to show rust. Im not sure why thought. Also my rims have a brown/black stuff on the dish part of them. I will try to post pictures of what im talking about. Any suggestions as to what to do?

 

as far as lug nuts most people use stock nuts, unless they have aftermarket rims I think there usually included. Also the black crap on your rims are probably brake dust, from either non metallic pads, or cheap metallic pads.
