I am including some background, it helps to know where the information is coming from. I've spent the last year tracking a 2005 Enthusiasts 350Z. In fact, during the last year I've spent 28 days on the track. I've been to Shenandoah, VIR Full, VIR South, VIR North, Roebling Road, Road Atlanta, Rockingham and CMP.
First I had to get the handling taken care of, then I had to resolve the brake issues. The handling part was pretty easy. I wasn't sure I would be able to find an affordable solution for the braking issues. I've used OEM pads, EBC Yellow, Hawk, Carobtech, and Racing Brake. I am VERY hard on brakes. I now drive in the advanced group and have to run with race cars, seasoned drivers, and big motors. The one place I found I can gain some time is braking. Instead of running 225 tires on the front, I am running 275's. These provide a lot more tire traction, which means I can put a much higher load on the brakes. I started out using the non-Brembo brakes, but quickly upgraded to the Brembo's using a set from a wrecked G35. Short summary of the pads I've used:
EBC Yellow - Short life, low temperature threshold
CarboTech - Noisy and expensive
Hawk HP+ - Nice track pad, but so noisy on the street I was embarrassed
That brings me to the RacingBrake pads. So far I've used their 700 series and their 900 series.
For the street and limited track use the 700 series are great. Although RacingBrake claims the pad make a small amount of noise, I haven't heard so much as a squeak from them. They hold up on the track for anything most non-racing drivers could throw at them. They do require a hard break in if you want to avoid any fading under track conditions. It was really nice to be able to drive the car on the street and on the track with the same pad. The pads had great modulation both on and off the track, and were very kind to the rotors.
Although I really liked the 700 series, because of the way I brake on the track I decided to try their 900 series as a track pad. RacingBrake lists this pad as a racing pad. At a recent Road Atlanta event, I knocked a second off my times by switching to the 900 series. Surprisingly the pad was fairly quiet on the street when I went for lunch and gas. I would not recommend this pad for street use as it is much more aggressive than the 700. By my measurements, it also has a higher rotor wear rate.
So which do I like the most? For all out racing, go with the 900. For anything else I would start out with the 700. If you need more, then go with the 900.
Note: You really need to follow the break-in procedures for these pads. They really need the heat cycle to to be ready for hard use. When I first used the 700's, I didn't break them in properly. They worked great on the street, but during my first track session, I was concerned that they might fade on me. Fortunately the first track session apparently worked as a good break-in. I had no problems during the rest of the event.
And no, I don't work for RacingBrake.
