Official reply from Wilwood regarding my particular brake kit.
Thank you for the inquiry with Wilwood Disc Brakes.
We’re sorry to hear that happened. Unfortunately this particular kit uses press-in wheel studs that are a one-time seat into the rotors; they cannot be changed once they’re pressed into the rotor. We have found that if the original studs are pressed out, the material/knurls of the rotor can become weakened, so the new studs may not hold the proper amount of torque. As such, you will need to purchase a new rotor if the studs are damaged beyond repair.
