So I broke a wheel stud and on the rotor I broke it I realized there is rotor play. I hope I'm exposing this right. The rotor can be moved in and out while the other 3 are flush. Is this directly correlated to the broke wheel stud?? Thanks.

 

the stud isn't there to help center the rotor during install. With the wheels on the car the rotor will be fixed and secured where it needs to be. That's why some cars have those rotors with the screw on them, to help with install. You will be fine driving around with 4 studs until you can get it replaced btw.

 

I thought so. Thank you. I actually drove about 300 miles with a broken stud. Since I bought some RPF1's that need front spacers I had to replace it.

 

a little side to side is normal
