Wheel hub 6th bolt
 

Hey guys I just bought some enkeis and they won't fit on my wheel hub because there is a 6th both sticking out.

​​​​​​I'm not sure what it is so I haven't taken an angle grinder to it yet, would new hubs fix the issue? I might as well because I need new bearings also.

Thanks for any help.

That bolt and spacer is intended to keep rear wheels from being incorrectly mounted up front. Use a little lubricant like WD-40 and a 10mm socket to remove it properly.

Or, if you're replacing hubs and rotors, just discard your old rotors and you no longer have that problem.

It's so you can't mix up front and rear oem wheels, if I remember correctly it comes off with a socket and a screwdriver to kinda pry at it

I did not know there were any Z's left that still had that bolt. LOL

Yeah that worked thank you very much
