I wouldn't alter the wheels that way for two reasons:

The first is structural integrity. I saw the drum of a wheel break off at the spokes In Blytheville last year. (SCCA National Tour) The owner had issues with his brake calipers rubbing against the spokes of the wheels so he shaved the back of the spokes. I realize you are talking about a different part of the wheel, but I still wouldn't do it.

The second reason is that any inconsistency in the new surface could cause the wheel to not be perfectly "plumb". -Meaning the wheel might sit at a slight angle rather than parallel to the hub. Even if you are only off by a little, it could create a noticeable wobble.

Great answer. Didn't think of reason two.

So you want to take metal away from the structure of the single most critical piece of your car keeping you from loosing a wheel and crashing? Sounds like a great idea...

Do it and let us know how it works out.

I don't mean to sound like a complete áss, but it's funny how we all become engineers at these times.

Shaving material from that part of the wheel to increase the + offset is something that has been done safely for years on many cars. Just can't take too much off.

It doesnt take an engineering degree to realize that any time you remove material from a structure, you weaken it to a degree.

How are you shaving these? a machine shop I assume? Cause that is the only correct way to do it. By the time you pay a machine shop to set up their machines and shave 3 mm you might as well have sold these and bought new ones..

If it were me, I personally wouldnt do it.

LOOOOOOL, you know the wheels are machined at the factory right? There are tolerances, and Rays/Volk likes making a "face" then add/take size from the hub area, so there has to be an amount that is 100% ok to take off. If Rays said the grade of their aluminum used I'd ask one of the engineers at work to work it out and tell me what is safe/acceptable

Machine shop, obviously. Cost? LOL, free, got myself a machine shop at work.
And considering CE28Ns in 19" are discontinued, it's kind of a bitch to find another set. Otherwise I would another set in a heartbeat

Let's SAY, I lower the car on swifts... Can I run the damn 275's?

CarbonFZ · 05-30-2014, 11:00 PM

It's fine but I think you can't do more than a few mm
