Can anyone tell me what this is/does??
 

So I am trying to install my new wheels and on the front hub there is a bolt that sticks out, i'm curious what it does?

My wheels don't fit around it, the socket on the wheel just barely makes contact.

I have a 2015 Nismo btw. Curious how guys with spacers and aftermarket wheels got around this. Can i just remove it?

Thanks

The bolt is to keep you from putting the front oem wheels on the rear or vice versa, remove it.

Edit: What kind of wheels are you putting on? and what is that gold/brown stuff on your hub?

Yup, just remove it. I think it's to help at the factory to make sure they put the rear wheels actually on the rears, but I could be wrong... Been a while since I've looked at them, since I took them off when I put spacers on and never looked back.

Thank you guys for the fast response I appreciate it :tup:

I have a set of Vossen CV5's from my old G coupe that im test fitting. But i believe its some type of anti corrosion? Im not 100% sure, this is the first time ive taken the stock whees off

huh, my Z doesnt have that gold/brown crap on the hubs. but if it is preventing corrosion dat's a good thing.

Cooper coat.

You can remove it. You'll be fine without it.

Bolts off and the wheels are on. My offsets are pretty weak on them, i pretty much used them to judge what I want to get next.

Im thinking a 20x9.5+25 front and 20x12+30 rear Vossen VFS1 in gloss graphite.

It would be the first Nismo on this setup

copper "grease", used on brake pad backing plates & misc pieces, doesnt hurt ,, just wipe it off.

Nope, not the first. F: 20x9.5 / R: 20x12

Those are the VFS2's.

I will have the first set of VFS1's in that size on a 2015 Nismo. I should have clarified, my fault

You are right. Google let me down.

Actually this is incorrect. These are a tool to remove the rotor in case it gets all rusty and won't come off. Unscrew that screw and remove the collar/spacer, then screw it back in. It will push against the wheel hub and force the rotor off.

They are indexing pins. See FSM.

How important is it to screw it back in? I currently have it taken out

Copy and paste from manual

Front and rear wheel size for this model differs, t
herefore special pin (1) is adopted to the front brake disc
rotor (2). And a hole (3) that matches to this pin
is adopted to the front wheel (4) (the rear wheel does not
have this wheel). This structure prevents the rear
wheel from being mistakenly installed on the front

Thank you :tup:

Actually Huck is correct, too. Unscrew, take off the sleeve, screw the bolt back in to remove a rotor when servicing/replacing in case it is stuck. I've done it before and works.

It is 0% important.

Yes, they can be used to help remove a stuck rotor, but, as per the manual, they were designed and installed to prevent putting rear wheels on the front.

Remove them if you like.
