I am running alum wheels. I am using a lock washer and a closed chrome lug. (lugcentric) My wheel studs don't stick out when the wheels are set on the hub. Are my studs long enough? Should the studs poke out from the wheel some? Would a longer stud be safer? I plan on using a .5" wheel spacer up front.... I will need a .5" longer set of studs... what size would that be? (length and thread) Who sells them? I am plannig on ordering all new studs (24). I am not sure of the size and where to get them. Opinions on stud size please.
