I had a machine shop redrill my new zimmerman rear 4lug rotors to 5lug. The holes are slightly off and the rotors will not sit flush--they hang-up on the studs. I opened the holes up a bit and it is much better. Unfortunately, they need even more opening which I'm concerned because to do this will make some of the holes loose around the studs. Is this safe?
Choices, do I open the holes up so the rotor will slip around the studs even though some of the studs will be sloppy knowing the wheel studs once torqued will hold things correctly? or Do I just go out and buy a set of 914-6 rear rotors and cut my losses? If so does someone have a source near Visalia, CA that I can get fast...I want to put my 5 lug conversion together this weekend? Pelican won't ship for 5 days. |

I would almost bet it's not the studs/holes.
Look for a ridge on the inside of the 914-6 or 914 rotors. This is something new in the Zimmermans and they don't like to sit on a 914 hub without grinding down that ridge. It's inside the rotor on the wall of the hat right down where it would mate with the hub. |
