You liked the PFC 11's? After years of loving 01's, I did one weekend on the 11's and hated them (stupid me I was actually excited to try the new and improved compound). No where near the initial bite, significant torque rise, and no where near the longevity. I even attribute my first off-track excursion EVER on those 11's.
I called PFC to complain and found they still had some 01's in stock so I bought a few sets. Unfortunately a month later when I finally pulled the 11's, I found one was separating from its backing plate (I would have demanded a replacement).
So is there an ST equivalent to the 01's at a cost savings?

I have never used the 01s. I like the idea of not having tremendous initial bite to try and prevent the anti locks triggering and found the PFC 11s to be easily modulated. OTOH as you have found, they don't last as long as I would have expected.
As a side note, using the KNS/DBA rotors (which are significantly different than stock in design), pad taper has been a minimal issue compared to using a stock style rotor.

Just checked the wear and rotors after a weekend of new ST43 and DBA rotors. Very impressed. Good wear of pads with virtually no taper. I attribute the lack of taper due to the design of the DBA rotor which is quite different than stock.
The DBA rotors are also sig. heavier than stock which may explain some of the better performance even if they are only stock sizes.
BTW the calipers are stock C5Z with no sign of spread that I can detect.
I know this is not as good as a BBK set up but it sure is better than stock and I haven't cracked a rotor all season

Which DBA rotor did you try?

Just a quick bump to my own thread... I ended up putting ST-43 pads on all four corners and running them for a weekend at Texas World Speedway. In short, the pads performed really well... I have no complaints and will buy them again.
I will say, however, that the pedal modulation issue is more prevalent than I expected. I got into ABS really easily, and at one point over the weekend I applied too much brake coming into a corner that just needed a small amount of brake to set the car and turn in. I previously ran Hawk DTC-70's and DTC-60's front and rear, so if you're used to that setup, you need to give yourself a few sessions to adjust to the Raybestos pads. Once I got a little smoother on my brake inputs all was well, and in the end I liked how they felt.
They also make more noise than the Hawk and Carbotec pads I've run previously. I don't really care, but it's not a pad I'd want to run on the street. They make a fair amount of noise even after being fully bedded.
As far as rotor wear goes, I'm not sure I can offer much guidance. My rotors were already heat checked and it seemed like maybe they were slightly more grooved at the end of the weekend, but I would have expected the same from any other pad.
What's really good is that they never even hinted at being over-temp on 200 treadwear tires. My tires would get greasy before the pads ever complained. They were strong and consistent throughout the weekend, and I never had any doubt that they would stop me from 130+ MPH.

Odd, I bought my Camaro with DTC70s and switched to ST43 and all of a sudden I wasn't flat spotting tires. Mine made noise when placed on a Hawk bedded rotor for a bit before bedding in and shutting up. That and cold weather is the only time I've heard noise from the brakes.

Did you feel it was the fronts locking up too easily or the rears?

Thought I'd kick this alive again rather than start a new thread since its been comparing different compounds.
I now have a few sets of PFC01's (stock calipers) so I'm set on the fronts for next season. I've been running PFC99's in the back and they have lasted a looooonng time but now need to be replaced (and no longer made). Anyone know the equivalent Raybestos to the 99?
I found a phone number for Raybestos motorsports dept but they said Summit Racing now handles their tech support. I thought that sounded pretty weird but I called Summit and was told its not the case and they don't even carry the pads for my car.
Anyone have a contact at Raybestos?

Call Tim at Porterfield brakes, I bet he knows.
