I have used them. As much as I like the PFC 01's, I thought these were better. Very high friction so you don't have to push your foot thru the floorboard. Really nice pedal feel, very light on rotors, very low pad wear also. I used the 47's at Laguna Seca, which is murder on brakes. Joe Gibbs Racing uses these pads(and the ST43's, which I have tried and are excellent as well) in NASCAR. Where are you finding them for $280 F/R, thats the price for just the fronts.

I used ST43s all around this whole summer; they were great and lasted quite long. After the 13th event, I realized there was uneven wear at fronts (I guess I should've rotated them; duh), but that's common for our OEM brake system. My only real issue (besides the obnoxious loudness) is that it felt like ABS was kicking in a bit too early. Thinking this might be caused due to not enough brake bias, I will use ST47s for fronts and see if I can have more deceleration without engaging ABS.
My rear ST43s still a lot of life left in them, so I will use them along with ST47s at the rear. I hope this combination works.
Once they're done, I might also try the Carbotechs. I have been turned off by their very short life, but since they are highly recommended by many, I guess I should give them a try and see it myself.
P.S. How were ST47s cold? I heard they need some heat; are they safe enough to drive to the track?

I drove them on the street minimally and they were fine (47 front, 45 rear).

[QUOTE=Ozer;1581737867]What did you use for the rears? I think Raybestos advertises ST45 as a great rear for ST47s at front, but I wonder if ST47/ST43 combination would work, too.
I just started using the ST47/ST43 combination and have been very happy with them. Big improvement over the Hawk HP+'s I'd been running -- no more hot spots on the rotors and much better stopping power.
No problem using them on the street -- cold grip is fine. Also, not any noisier than the Hawk's, but they actually have a two-tone squeal for a little two part harmony when you come to a stop.
You'll want to take it a little easy your first track session with them, to get them fully bedded-in and get used to the different noise they make (high-pitched squeal on heavy braking). But then you're good to go.

Glad to hear that this combination works. I'm also glad to hear it felt safe enough for street use. I stopped going back and forth between race and street pads this summer since it quickly gets boring. It would be nice to keep them on and annoy my neighbors than get annoyed changing them all the time

Ok. I will check it out right now!
***Darn! No luck there for my C6Z06. Didn't think about it, but that price was probably for the C5/C5Z06/C6 pad fitment****

I've just recently tried running ST-47's up front with ST-43's in back and was very pleased with them. Previous to that I had ST-43's up front as well. The pad life seems very good and they have been easy on my rotors as well.

(1) How is the front/rear bias? Did it feel like stock, or did fronts or rears lock-up first?
(2) I was told that ST47s need a bit of heat to work. Did you try it on the streets? Was it at least OK?
(3) How is the pedal feel compared to ST43s all around?

I run the ST47s up front but non Raybestos in the rear. Compared to the ST43s, I thought the pedal felt even better than my previous memories of the ST43s. IMO they are very high friction compared to most other "race pads" so the pedal has a light feel for the amount of stopping force, very progressive. I hate those pads that require you to put your foot through the floorboard.

I have driven ST41, 43, and 47 on the street with no issue. All need heat to work well on the track, but are fine on the street.
