Ball studs?
 

What are the longest ball studs that fit the rpm cups i hav the associated ball studs the .300 ones and they are not long enough to go through the camber plate and to add washers to on the 210 any help would be appreciated. Wat other brands do the rpm cups fit onto schumacher? HPI? Etc thanks in advance

You should find what you need right here.

Would measure them in the shop though just to make sure.

Oh, and using the long versions might even eliminate the need for some washers aswell.

HPI86896 do these fit rpm cups and is the threaded part 12mm?
