what studs?
Also, if you're changing studs in axles you already have... a press-in 3" x 1/2" stud will need a .610"(39/64) hole for the knurl.
You can have the axles drileld so you can run a 1/2 inch or stock sized stud, and a 5/8 stud as well, just have to have moser drill them for you that way... then you can change them to whatever you want. Seen that done a couple times.
and i have 2 sets of rear wheels for it ones for the track are jegs prostars and the street are matching greg welds. i might go the other way but i havent decided
