just make sure for the love of god u fully drill out the old threads. i sent my hubs off to have the work done, and somehow 1 of the holes was missed, and a stud was pressed in with thread still in place. result, 1 cracked hub

for such a cheap and simple job, it dont half make a world of difference though. no more fighting to line up bolts thru constantly spinning brake discs, and fighting to hold a wheel in place whilst u try and find all the bolts lol
