Need new stud, also brakes shaking a bit, player a bit of help? Options

[Digndoug]

Ok I bought axis pads and the, cant remember the brand, sloted rotors from nopi.com. I go them installed, I noticed after the install, that on highway speeds im getting a little bit more shaking. Im not sure what it is, I also broke a stud on the front left, but still have 4 bolts on, which should be fine.

Also whil looking for imput, i need a new set of locking lugs, the old ones i hd were crap. any sugestions?
