Anyone know what this thing is? Never seen anything like this before.

I was trying to install some winter wheels on my G and they don't fit because of this thing... The wheels that i bought came off of a 2003 G35 coupe - so i am a bit curious as to what this thing is and if it is on all G coupes...

maybe brembo brakes? idk though, never seen them up close before.. but just my .02

 

that thing is for you dont put your rear rims in the front of your car..you can take that bolt out...

 

just unscrew it, it's there to prevent the stock rear wheels being mistakenly put on the front since on the coupe's it's a staggered fitment, cuz you know shops sometiimes do wheel rotations and sometimes they're too dumb to even know what a staggered setup really is, and this was put in place for idiots like that.
Like I said, unscrew it and slap on your wheels. I just did it a few days ago when I was putting my wheel spacers on

 

ppo here thinks it is to prevent owners from putting the rear wheels onto the front... i use them to help remove my rotors if theyre stuck too tight.....
just take em off and you'll be fine...

 

yup...

useless...

 

SWEET! Thanks guys - i was pissed off because i just bought some winter wheels/tires and i thought i was gonna have to sell them!

Thanks for the quick replies!
