Recommended Brake Pads

Well lets see.....I went through 5 sets of front pads on my rotors this summer..3 sets of HP+ and 2 sets of Hawk Blacks.......rotors have no heat checks...and almost no wear.....as you can tell they probably aren't stock.......but I don't find the HP+ that hard on the rotors....

your gf has and rx8. you have a z. you have a friend that has an 8 that you track, but at 9/10ths...
you answered the track ?s right i have no reason not to trust you. but you came so out of the blue...
and what car is this.... it is an rx8... you have a track rx8.
i think i am lost now.
never did lime rock. but braking on the mouse head going into the loop at the glen is odd the first day.

Indeed, that's the front of a Z. And a 2003-2005 non-Track model to be specific. It's not just the rotors that suck, it's the entire braking system! Those cars have criminally undersized brakes from the factory, that have the added benefit of feeling absolutely terrible when you are on track. Yes, I know this from experience 
. In fact, we're working on our own Z brake kit right now after experiencing both fitment and operational failures with two other BBKs on the market for that car. I'll only say we didn't try Stoptech and should have gone there first, but live and learn.
Noted that someone asked about the friction coefficent and temp range of the OEM pads. Unfortunately I don't know the answer to that question, but typical OEM pads are good for around 600 degrees or so. The RX-8 OEM pads seem better than average, so perhaps 700? Just guessing at that. Keeping in mind the RX-8 brakes are quite large for the weight and speed potential of the car, so they tend to stay cooler than most under similar conditions. On the friction coefficent, I won't even guess. They seem to bite fairly well, really, but certainly aren't as aggressive as a race pad.
Also, something to know about friction coefficients is that there's no standard way of measuring it. This is why many companies are reluctant to publish the information. Carbotech used to, but doesn't any longer because between companies you're not comparing apples to apples. The numbers I quoted for them are accurate and were taken off their site before they removed the numbers, but only use them to compare between Carbotech pads. In general, Carbotech bads 'bite' fairly aggressively once they have a bit of heat in them, and more importantly have very good modulation and release characteristics. To summarize, they inspire confidence and provide excellent pedal feel.

I own both a RX-8 and a 350Z (my track + DD), the RX-8 is left for the fiance to use. My RX-8 experience came from my friend's car and a few student's car, that's why i am not a track rookie in the 8.
Going back to brakes, the wear rate between both cars are different, but you can see the wear on the rotor. All things consider, the front rotors really arent that bad. The rears were fine until I put the HP+ on. I will snap a photo when the car is in the garage.
Lime Rock is just plain scary at this day and age, the track surface is worse than Seal's face. I don't think any tracks are like it with the exception of Sebring. Maybe Mosport with bumps. Glen is different, it's more like VIR except less run off area.

The brakes are absolutely terrible and are subject to high heat abuse. If you have to keep the car stock, performance pads is the only way to keep your brakes in one piece. I can do about two to three hotlaps before I lose my pedal. One cool down is what I need to bring them back under control. The other sad part is that they last 250-350 miles in the front, 200-250 in the rear. Left over parts suck!
Many people might not believe this, but the car can still hold its own under braking (when they are cool). The Brembo just help prolong the life of the brakes and they do work a little better. It really isn't a big deal as long as you dont mind changing pads every 2 to 3 events. In the last time trial at Pocono in September, two of the cars in the top 4 were non-brembo equipped Z.
Back to RX-8 brakes, I had no major problem with the brakes even after the 20 minute session. With the stock pads, I did have to pace myself from time to time to prevent them from overheating. We got about 600-700 miles on them before we killed off the stock brake pads (car had about 8000 miles on it)

Great thread. Just ordered Bobcats for my front brakes. WIth so many TSB's that have to be done I was going to have the dealer install the brakes using my pads -I just hop ethey dont try and sell my on replacing the rotors just to make extra $$$ - any clues as to how I can tell if they are bullshi**ing me?
