I have H&R 10mm all the way around. Installing my stud conversion this weekend, can't wait, will finally be able to pull wheels off for cleaning without it being an absolute chore. Only worry is I was only able to find wheel nuts from Gorilla, and they are not open end, could not find any. So not sure if they will work or not. Hard finding ball seat stuff that works, conical seat stuff is everywhere. Oh well, fingers crossed, if they don't work then I will just wait for the new wheels to get here which are conical seat.
