David Bongiovanni from Goodsport Racing reviews the RacingBrake ET700 and ET900 brake pads:

I'm one of the people that has been testing the Racing Brake ET700 and ET900 pads since last year.
Our first outing was the 25 hours of Thunderhill in my 270 whp full race Evo. The car uses stock front calipers and Racing Brake four piston rear calipers, with bias control. We managed to run the whole race on one set of pads (using only 1/2 the pad material) and placed 2nd in class E0. We were running at a relaxed pace, and the pads worked wonderfully with no fade, exceptional life, and no noise. After the race I drove the car about 100 miles on the street and can verify other's observations that these pads are totally streetable with no noise and low dusting.
The second outing was a three hour enduro at Sears Point/Infineon. This race was run at full pace and again the ET700 Compound performed well with no fade and exceptional rotor wear. In fact, the Racing Brake two piece rotors showed almost no measureable wear after 30 hours of enduro track time using the ET700.
An Evo with stock calipers can push the ET700 past its service temp of 1400 degrees at tracks like Thunderhill and Laguna Seca, though I can attest that the pads approach this service limit progressively and give plenty of warning as they begin to overheat.
As an alternative to the Hawk DTC-60 usually required, Racing Brake provided the ET900 compound for the next test at Thunderhill. Two 1/2 hour races produced excellent results. After a proper bed-in the pads felt ready for a proper workout. They heated up quickly and developed good initial bite that became excellent at high temperatures. Modulation was excellent, as I felt like the bias control was working exceptionally well, an indicator that I was really able to feel what was going on at the contact patch.
I drove the wheels off the car, turning a 2:01.5 laptime in the 3300 lb. car, and these brakes performed exceptionally. Rotor wear was higher than with the ET700, but still lower than I've seen with any other full race pad. There was little noise, with absolutely no squeeling whether cold or hot.
I'll be driving the car on the street soon to see if they are still streetable after they rest for a few days, but I think they will be. Driving around the pits produced no noise at all, just a little gravely feel reminding you of their agressive full race potential.
Two up from me. I'll be using these pads from now on, and I can get any pads I want for free, so I only use what performs the best.
