I couldn't agree more with what JCL said.

I have the Centric plain rotors (from Dave Zeckhausen) and I bought Axxis XBG pads from Turner Motorsports. The XBG's are in the middle of the the Delux and Ultimates with regard to dust and performance. I got 4 rotors, 4 sets of pads, and wear sensors for $420.

I haven't noticed any significant increase of dust over OEM and performance is as good or better than OEM, IMO. THe Centric rotors also have a black coated hat that looks good and prevents that ugly rust from forming over time.

Good luck.
