Kevinkay has seen scoring and signs of overheating running Akebono pads.
Posting pics so he can see what mine look like with over 1.5 yrs and 20k miles of use, HARD use a few weeks ago (hot lapping Sebring track with 5 people in the X & a few hard stops from over 130 mph to 50 mph).....

Figured I would update wear numbers after over 2 years and 35k miles.
Rotors new were 1.2, now measure 1.17 (.03 thinner), that's only .015 per rotor side. To say Cool Carbon pads are rotor friendly is a MASSIVE understatement!!! The pad thickness is over 5/16" (.312). Didn't measure pad t'ness new but would estimate this is around 1/2 pad life. I have no idea how some have stated excessive dusting, when so little rotor/pad material has worn in 35k miles. When these had 6 months and around 10k miles, I found the 1.2 rotor thickness was down to 1.185 (.0075 worn per rotor side). That 1.2 new measurement was taken on the soft Zinc plating surface which wore off during initial bedding, so actual rotor wear was lower then .0075 in 10k miles. I would put this rotor/pad combo up against ANYTHING short of carbon/ceramic pads/rotors for longevity.

To second TiAgX5's sentiments....
Sunday, I just put a new set of CC's on my rears because I like them so much up front. The feel is just fantastic (for me anyway). I haven't measured the fronts, but I'd wager they have at least 1/3 life left after about 18k miles. I am thinking I'll probably get 30k-30k out of them. Dusting is such that...well...I just don't notice it. That's the big difference. I have always noticed the brake dust and it drove me nuts. It requires a LONG absence from the car wash before the CC dust starts yelling at you to wash it off. The other big thing about these is...I have stopped wanting to shop/try/compare other brake pads. When I get my next set, I won't look for anything else. That's saying a lot.

I was impressed by the CC pads on the E46 (with track days each year), the E53 results have made pad search a thing of the past!

wow, what a huge difference I experience with these Cool Carbon's and new Centric rotors.
still LOTS of brake dust, more grey/brown instead of dark grey/black of OE. And I believe because of temps up here (being cooler than placer closer to Equator), they do NOT stop nearly as well as OE does for me. I have to ride the brakes to heat them up to get them to be useful. I also find it a bit foolish that after every 6 months you should do the "break in" procedure again. I never needed that for OE pads. Just saying my experience with this brake set-up in the Cooler area North of the 49th (yet still a warm city compared to MUCH of Canada).
