That's funny.

"no warranty because racing. BUT I LIKE racing, so i'm going to send you hubs anyway."

Thanks for following up.

Now that's customer service. Some vendor should be taking notes on how to engage with the customer.

Lol just saw this. @hi_im_sean

That's awfully nice of them. Maybe you can compare the 100% legit Timkens versus the Rock Auto ones. I'd be curious if RA somehow ended up with knock-offs.

I'd be fairly surprised if RA sold me something else in a Timken box (edit: come to think of it they have fucked up some parts I've ordered before..), but as I posted earlier the $20CAD/each uber cheap Chinese stamped RA bearings don't have this machining feature so I don't believe that's the case. I think this is a ABS hub feature as someone else alluded too above.

Props to Patrick for being cool anyway.

You should email him a link to this thread.

My free hubs came in, going straight to the garbage.

But why?! Machined sharp edges and stress concentrations.

From what I understand Rock Auto is just a network of auto stores selling their parts online and "Rock Auto" themselves never actually hold product.

I had a few discussions with our sales department about them at my last job and they are not officially a customer so it's impossible to enforce MAP pricing.

Jeez!

Strike Timken.

So far so good on my Mazdaspeed HDs. 1 track day at MSR-C (1.7CCW) and 2 at Hallett (1 CW and 1 CCW).

As another data point, I went and purchased new Duralast ABS hubs at autozone. No machining where the studs go in, but.....

Dafuq? Why would they machine them there?

notable markings?

@OGRacing do your auto zone parts store hubs have this machining on them?

Somebody in China is confused.

I have some Detroit axle front ABS hubs.

Almost all of the ABS hubs have that second machined section, which is why I'm ---- about getting non-ABS hubs. It's for a different tone ring that's shown in some of the pictures. I assume it allows the miata hub to be shared with some other vehicle.

Interesting. Jpreston, it looks like the Non-abs hubs you got were still machined for our tone rings.

I have some non-abs Detroit axle front hubs at home also. I will snap some pictures of those tonight.

Do you guys think that second set of machining is a problem? Are OEM ABS hubs machined there? Don't have one handy at the moment...

Still paging @OGRacing to see if his surprisingly durable ABS Duralast hubs have the same machining mine do.

I hope so. I'd like to run them. Only paid $46 apiece for them.

OEM hubs do not afaik. I will check min tonight also.

oh sorry lol. the hubs are on the car. thrashing now to get it ready for Octoberber Nasa @road atl. If i get a chance I'll see if i can shine a light in there.

Pretty please.
