If your rotors are fucked and you're looking to do this on the cheap, get something like the Centric blanks. Much cheaper and they'll do the job.
Also, if the rotors don't wanna seem to come off of the hub, you'll need to thread some metric bolts into two little holes on the rotor hat. I don't remember what size the bolts are just that they're metric and you can get them at ACE hardware. I pounded on my front rotors until I broke them and they never budged. Threaded the bolts in and the popped of in 30 seconds.
Hmmm...I'm not totally sure what you're talking about, but I'm sure I'll see what you mean if I have to change the rotors in which case, I will refer to your post...as I often do.
I'm quite competent in some areas and retarded in other areas. :doh:
By the way, are factory replacements expensive?
EDIT: When I bought the car, I made a deal with the stealership, that if I was going to buy the car, I wanted it inspected by a third party and anything fixed that was f-ed. The front rotors where a bit warped so they changed them for me. 10 minutes after I got off the phone with them about the rotor replacement, the parts guy called me back and said "believe it or not, the factory drilled Brembo rotors are the same price as the original rotors, do you want those?". Of course I wanted those. So that's what I have up front.
