I'm replacing all the rotors and pads on my 06 R53 today. Last time I had the wheels off, I noticed the set screw (I think that's what it's called) on the rotor that holds it in place on the hub is stripped. I think I can order new ones from my dealer, but that still leaves the issues of removing them.

Do you guys think I can drill them out and remove them? Is there any chance someone here knows the size of the screw so I know what size diamond drill bit to pick up from the store?

Thank you in advance for any help and advice you guys might be able to give me, I really wanna throw these drilled and slotted rotors and ceramic pads on!

 

I would probably drill them out to remove the head of the screw that holds the rotor to the hub and then forget about replacing them and drilling out the entire screw. You don't have to have them, they just aid in holding the rotors on while putting the wheels on. Once the wheels are on the lugs are whats actually holding the rotor in place.

If you must, once you do get them head of the screw off and the rotors off, I would imagine with enough WD40 soaking and a vice grip you would be able to grab the stub and turn them out. WD40 to penetrate the corrosion as well as a blow torch separately to heat the screw stub will also help.

 

I was debating just leaving the new rotors on without the screw. Seemed like it'd be solid without the screw since the lugs and wheel will be on there.

Thank you sir

 

Don't know the size, but I had to cut one of mine out with a rotozip and some metal bits. Just had to keep working on cutting away material until I had created enough of a surface to loosen it with a screwdriver. Ditto on being able to drive without it.
