ECS tuning sells a conversion stud and lug nut set, one of the most satisfying upgrades one can perform.

Have any reason they are the worst design failure? I have yet to have one fail in 20 years (holy crap... time is flying) of driving BMW's. Working on at least 50+. Have worked on parent's/friends vehicles that use studs and never found any advantage to studs/nuts vs lugs.
Sorry OB, no ideas on the 19mm vs 17mm head size. Make sure your wheel can accommodate a 19mm socket and not need some super special thin wall socket to be able to remove the lugs.
My Forgestar wheels can BARELY use a 19mm socket. Barely. I use ECS tuning 15mm spacers and extended lugs on Red. They are 17mm...
