Does anyone know how or ever drilled out 4 3/4" rotors to 5 on 5? If you can is there a easy way of doing it? Use something as a pattern, etc? Or does anyone know who does that at a decent price? Please post a reply and let me know or email me at smaldirt128@hotmail.com. Thanks in advance.

You might be better off buying those aluminum adapters. They are $50 or $60 a peice but I use them and have never broken one. It would also make your front end 2" wider which with a metric chassis would be a good thing.

As far as drilling them out yourself, I have never done it but you might be able to put a wheel on your rotor and drill through the rotor that way but it might not be accurate enough.
 
You can drill them yourself. It is quite easy if you have the jig and a fly-cutter. You can pick up the jig or pattern wheel as i have heard it called before at most trade shows. Use a good 5/8" bit in a drill press (don't try to hold on to a hand held drill) and go slow. When all holes are drilled then check to make sure the shoulder of the stud fits all the in (generally you have to fly cut these) once you have the materials to do this you are good to go. And to make a little cash too!
 
I posted on the classified to this before I read on here I can drill most rotors for about $20.00 a piece its fairly easy with right tools but takes a little time. Also I make the adapters for about $75.00 a set depending on material prices I try to use scrap pieces for this cause you only need to be an inch wide. prices can be cheaper depending if guy supplies his own studs.
 
You need to use a 43/64 drill bit, and I have found the easiest way to do it is to bolt on a wheel spacer that is made for both patterns. Using a drill press, it isn't very hard at all.
 
Yeah Dean you are correct on the 43/64" drill bit. I just bought a brand new one not too long ago. Do you think it would work if i use the center of a 5 on 5 wheel that is bent. Just cut out the center of it and maybe center it and tack weld it on the rotor so it doesn't move and use a drill press to drill them out then? Sounds like it would work to me? What is your thoughts? Thanks everyone for the replies though. Thanks again.
