Increasing whee stud diameter

[jeremiahnz]

Hi,

I have performed a drum to disc conversion and need longer wheel studs. The previous studs were 7/16” however as the rotors are drilled to M12, I would like to get the axles/hubs drilled out slightly (by an engineering shop) to accept a M12 wheel stud. Is this something that can be certified?


It is an old car and replacing hubs/axles would be difficult as they are hard to find, so want to be sure first!

Thanks

No problems with what you are suggesting, providing it is modified in a tradesman-like manner.
