Hey Bart,
I went through a similar decision making process a few months ago and I decided to go with the following:
SP Performance Rotors:
Front: Diamond Slotted
Rear: Slotted
SP Performance Street Pads
http://www.sfxperformance.com/parts/...tems/index.htm
I chose these because they came recommended by several of the veterans of this site, and seemed like the best bang for the buck. Unfortunately, they would not do Diamond Slots on the rear rotors (and wouldn't explain why), but otherwise I think this is the best deal available if you can afford them.
P.S. - No discredit is meant towards R1, BTW. I have never used them, nor know anything about them, besides the fact that a few members here have expressed good results with them. I've never heard anything bad about them and they are very reasonably priced.
