Yes, but it is only them making them. Until BSR, CRC, Ulti, etc make them, they will never be used at an event, unless Schumacher/Contact RC is the race sponsor. And then no one would show up until the other manufacturers change as well. I like the idea, just think it is not really an issue that needed to be fixed. Going from 2 bolt to 3 bolt was due to not having to reset/rebuild your diff every time you changed tires, not for being lazy, lol.
