53K and still on original set... Pulled and checked at 50K, pads still are about 6mm think...will buy a set of Hawks soon and do them myself, have a pro shop here than can turn the rotors, just did ones on my buddies Z and all is well... Rotors look great!

 

Yes, I run Project Mu HP Titan-Kai pads on all four corners. Its almost a race pad, but still kinda inbeween street & racepad (I track my car)
I also have StopTech 2-piece Slotted (not drilled) AeroRotors all around.
I also did the StopTech Stainless Steel Brake lines and Motul 600 Brake Fluid.

A few comments:
I did everything myself at about 20K miles. The OEM pads would have lasted me a while longer (maybe to 25K), and the rotors were just fine. ..but I had a trackday coming up so I just did everything - Rotors, pads, lines, fluid.
The car stops better. I didn't even want to believe it could stop better (I LOVE those Brembos), but it stops shorter nodoubtaboutit! I'm very happy with the performance.
If you compare the weight of the OEM rotor to the 2-piece Stoptech rotor (with Aluminum hat), the difference is incredible! The 2-piece are much, much lighter!
A squeeel is still there, but it is a different squeel. My OEMs squeeled while I was going slowly and my foot was off the brakes. My brakes now squeel as I brake from a slow roll to a stop. It squeels bad, too.
The brake dust, well, I might say its just a little bit better. Not much better, but a little bit perhaps.
But I can live with squeel and dust in exchange for the braking performance I'm getting.

 

Had the front changed at about 31K-32K. Had the rears changed when I took her in for the 45,000-mile service. Hawks hps all around no complaints yet.

 

I used Satisifed Ceramic pads all around at about 40k mi. w/o any need to resurface rotors....great pads, almost no dust/squeal and under $100 bucks for da whole set....
