For me, this comparison is more of a cost thing. Right now, I think the Pagid Yellow has established itself as a top tier track pad with the lowest operating costs. That's just from my observations.
Which pagid are you using, rs19? or rs29?

I did the comparison this weekend. I have to measure my pads and rotors tomorrow.

I like ST SR34s for the track and I like them better than the Pagid Yellows as far as performance. I shaved almost 2 seconds from Sat to Sun. Some of that was my NT01s getting a little grippier. I was braking later with more confidence. They were also easier to modulate and trail brake. The pagids were grabby but as I buried they pedal, it seemed that the torque was constant. These SR34s seems to add in torque as you squeeze the pedal. I'm a PF01 fan so if you like the PF01s, then the Stoptech racing SR34s are an excellent alternative without the noise (so far).

The bad, they are super touchy when cold and on the street. Its almost undrivable in stop and go traffic for me.

I'm more concerned about wear rates though...more on that tomorrow.

Thanks for the update. Sounds like a winner. Would you stick to the same compound if you were buying again?

I'm about to hit COTA this weekend with PFC01's. They're an awesome compound.

Did you get the sr34's direct from stoptech? I wonder if they have them in stock

Performance wise, definitely! I'm more worried about the budget aspect which is the only reason I'm looking beyond the PF01s. My opinion is that if I were raised on Pagid Yellows, I'd love them because they are awesome pads. I was raised on PF01s, I love them because they are awesome pads. Both just a little different. Is there a definitive better one? That is in the eye of the beholder.

Keep trying to remember to tell you...your company was listed in Family Handyman. Not sure if you knew. Sorry for hijack.

Cool. Let me know if you need to ship them to me. I would guess that you are traveling.

Is it cool if I get there around lunch time? Or I can pass them to someone driving the day before.

Either way works for me I appreciate it! I can't believe they don't allow passengers.

COTA is super strict especially on track. Don't even get close to the blend line.

Here's a summary of the data. This was done on Motorsport Ranch Houston, 2.4 CCW. Sat and Sun weather were similar in temps and conditions. Sun saw some rain and 3 wet laps. Measured with the same caliper, zero'd after each measurement. Measured each pad in 3 places in the middle of the pad from top of bottom. All data is based on the front axle only. I do have NT01s, some of the time improvement can be attributed to the tires wearing down since NT01s get sticker. They still have the horizontal tread though so it didn't turn into a true slick.

The pagids saw 22 laps. They wore on average about .4-.5mm each pad. The rotor saw about .05mm of wear. I did 9 of 22 laps under 1:50 with a best of 1:47:26.

The stoptechs saw 31 laps. They wore about .8mm each pad. The rotor saw about .05mm of wear. I did 16 of the 31 laps under 1:50 with a best of 1:45:68 and a 1:46:6 and did 5 more laps in the 1:47s.

My conclusion? There is no clear advantage in wear rates. For me, who has been raised on PF01s...the Stoptech SR34s have a clear advantage in performance for me. The pedal was better, there was more torque as you add brake pressure. I liked trail braking with the SR34s better as well.

Most of all...when you threshold brake, the car doesn't wag. If you know MSRH, you go through gut check which is a flat out right then left hander into a hard braking zone followed by a double apex 180. With the Pagids, I had to straightline brake. No trail braking here...I would have been in the gravel. The rear end wagged and I had to brake at the second apex. This is where the clear performance advantage came. With the Stoptechs, I went what I would estimate another car length past the same apex, got on the brakes and trailbraked deep.

I'll post some long term wear rates (# of days) a couple of months from now. The only way pagids can win for me is if they last a very, very long time. But IMO...the Stoptechs are a clear winner for me. Cost, performance, and at least from this short test, wear rates. The SR34s instill performance, feel, and confidence.

Don't know...never been black flagged for a non-spin until this damned weekend at a different track! Guy decided to blend. I was going about 90 entering a fast corner. The line blends into a corner and I passed him when he was about a car length past the end of the blend line. I would have had to hit the brakes pretty hard. That's neither here or there...

The organizers at the Driver's Edge event were VERY specific about the blend line. So I would assume that they'll have snipers at T3 take you out if you cross the blend line.
