Wheel shaving?
Don't want to diss any vendors but there is currently one (commercial vendor forum) offering to take 3mm off the bolt surface of a wheel for better fitment for the 1series. I have never heard of such a thing.

Interested in a response (possibly from tire rack) too. The wheels are cast or forged for certain tolerances. I would think that "shaving" could easily compromise structural integrity.
Unless the manufacturer blessed the "shaving", it sounds really dangerous to me.... but what do I know? :iono: |

so why not shave the hub?
But also i would assume a forged wheel, especially the "forged stye" wheels that are now popular that are just machined blanks could tolerate a couple mm's. but youd have to have confidence, and i dont know how you could mount it on a lathe. Or now that i thik of it it would be somthing mounting a wheel on a lathe wouldnt it. Id probably have a friend whos a cnc guru do it, but i dont know how else you would. |

Talk to your manufacturer and see what they recommend. Don't take what I'm saying as a end all to the question. I'm sure most will recommend against it.
I've had the backpads on a wheel shaved before. The manufactuer told us that 3mm was the safest limit that we could shave without sacrificing structural integrity. It was for this one particular wheel, so YMMV. |

ulrichd, shaving your wheel is possible, and it does happen. We have shaved wheels before, but it is definitely a process that you'd have to consider before you take the plunge for it. Once you do it, it cannot be reversed.
The amount of the hub that can be shaved depends on where the wheel is manufactured and who manufactures it. Either way, it's typically minimal on how much you can shave. There is a certain amount of the hub you can shave before the structural integrity is compromised, but wheels, like our Miro wheels for example, can be shaved 3-4mm at most until the structural integrity is compromised. We do not recommend it, but if a customer asks for it to fit, we do offer this option. You should definitely do research on the wheel, talk to the retailer/manufacturer, and look into cast/forged wheels before you do shave the hub. |

The custom cut wheel faces you are talking about do come out as a rough casting that can accomodate almost any offset. The problem is when they drill the wheel, they counter sink the face side for the lugs. This is where the real offset is "set" and where the danger comes in when shaving the backpad of the wheel. When you shave the backpad of the wheels you are making the "meat" of the wheel thinner where the lug holds the wheel to the hub. But in all honesty, I don't reccommend that you guys attempt to get this done unless you get it straight from the manufacturer. Your machine shop isn't going to question the amount shaved or even have second thoughts about the integrity of the wheel. They are just doing what you tell them to do. 5Zigen did some custom offset wheels for us once on this demo car we had a few years back. But remember that this was all handled by the actual wheel company, not a 3rd party. |
