Read the post below (from Tuesday)the information is pertinent to this discussion.
1) I'm being quoted close to $1000 at a BMW dealership. Is the standard?
Answer: From the typical stealer - yes. The rears were quoted by a dealer in the below post for about low $400s. The front rotors are more $ then the rears and then add f/r sensors (about $15 from dealer, $10 mail order) and then bleeding/flushing brake fluid. Therefore, I can see that it would add up to $950-1000 from the typical "stealer".
2) Are there places that it can be done cheaper?
Answer: Yes - Go to an independent. Buy your parts mail order from anyone of the good suppliers available. Go to the BMWCCA website and check out the links. Many good vendors available. Or mail order from Nick Alexander BMW in LA. Take the parts to an independent mechanic or the dealer. They will do the labor and you save $$$ on parts. Or better yet, learn how to do it yourself - very easy to do.
3) I've been told that the rotors can't be turned/shaved/straightened. Are they trying to sell me more stuff or do you generally replace the entire brake system at one time?
Answer: From my past experience and with 37k miles on your car, your rotors are TOAST! I bet they have worn at or below minimum thickness. Get new rotors for your situation. Yes rotors can be turned/trued as long as they are within specifications (front new is 28mm, min. is 26.4mm). The only time I turn them is when they are fairly new and need to be cleaned up, do to extensive track time. Sometimes after hard track use, spiral grooves or slight warpage occurs that can sometimes be corrected with turning the rotors on a lathe. I have two Euro front rotors I am getting turned today, after some previous track use ($7 each at local brake shop).
Michelin Pilot Sports are great tires, but not for me. I think the supply has been unreliable in the past, not sure of now and future? Michelin pissed me off when I could not get rears when mine were worn. Had to buy four new tires. Went with Bridgestone S02s. Kinda glad, I overall like the S02s better and a little cheaper. Also, I heard many good things about Yok AVS Sports, and they are much cheaper. Depends on your requirements. I want a good handling dry, but need a very good wet tire - S02s are perfect. I might go next with Dunlop 9000 hydromax, since they have twice the wear rating. I only got 9k miles on the rears from my S02s. I am on my second set of rears and first set of fronts.
Hope this helps and if you are not a member of BMWCCA, please join. I am an avid supporter and am trying to get more people to join. No personal gain from this, only gain for others.
