you will not be able to do it safely. once the center is redrilled or reweld, it weakens and makes it dangerous to ride on. may also crack from stress even causing your wheel to fly off. for the cost of doing it if any shop is even willing to, your better off buying another set of wheels plus eagle wheels are cheap anyways. i had a shop bore out a set for me once from 4x? to 4x114.3. the holes started to crack even with a sleeve insert for strenth. lucky i saw it before it gave up on me. alot of custom wheel shop i talk to say its dangerous and is same anser you will probably get.
