I just replaced last month all the rotors and pads. I do not track all, I just wanted a smoother stop since my Boxster has 68K on it. I purchased my parts from Pelican Parts, Balo rotors and Mintex pads. She now has a very smooth stop, it was a major difference. Rotors and pads plus I flushed my brake system...spent about $450. You do not need to buy caliper bolts. Use a good Locktight on the threads. The Balo's are German made and I compared to the one original ones that I took off...they were the same.
