some advice. if you are going to do it yourself.

heat the rotors up as much as possible (within reason)

then drill the holes.

the problem with MAKING new holes in rotors, is, if the metal is cold, its more likely to create stress fractures and fissures in the material.

which can lead to a hidden crack, then sudden break in the rotor.

a good machine shop tech should know to do this.

 

I had mine drilled at a shop in Norfolk before I moved here to NOVA... I can't remember the name though, my boss refered me. Shops are out there, sorry I can't exactly say which one. I wanna say AJ's but I'm not sure

 

L&W machine in Norfolk will do it for you
