Nice! Yea, your data points will be much more valid than the DE champs not getting anywhere close to peak slip angle hohos. Definitely keep us posted!

LMFAO!
I recognize these people as wearing full nomex while driving a street car or most beginner Ferrari drivers!
I hope that this did not start as a shot at me checking the bearings at 2k miles! I have always been fanatical at car prep...its what I was taught and what I experienced driving for a manufacture. Of course the driving that I did was MUCH harder on a car.

This is a great thread that I refer to often. It would be nice to add cold and hot temp targets for the commonly used tires - Dunlop, PSC2, RE71, etc. My recent experience with the Dunlops has been 26,28 cold - 31,33 hot seems to work well.

I have been trying to do more research as it relates to track day pads and how they compare to each other. Here is what my data has turned up thus far.
Track Day Pad - Common theme, all have little wear on the brake rotor or have long pad life
Reporting breakdown follows this scheme: Brand > Line > Torque Range reported in (Mu) > Working Temp Range > Notes
Pagid > RS29 > .38 - .45 > 180-700 C > Peak Temp at 500C before brake performance drop off
Pagid > RSL1 > .45 - .53 > 150-650 C > high bite; a tad more than Ferodo
Endless > ME20 > .35 - .40 > 150-800 C > 100C higher performance area than the ME22; good in wet and dry
Endless > ME22 > .33 - .38 > 150-800 C > less bite, but flatter torque curve; good in wet and dry
Ferodo > DS1.11 > .40 - .50 > 200-700 C > average mu .46
RT > RE10 > n/a > n/a > average mu .39; dusts less than other RT pads; low heat pad that works for OEM applications
I was hoping someone would be able to contribute more to the RT RE10 pad. Please note these values are taken directly from official company publications (ie brand website or detailed catalog) - NOT taken from what people report on the internet.

I used the DTC70s for 5 years on my E90, and I think I went through just 3 sets of OEM rotors doing 8+ track event per year at TWS. With SRF and NT01s, I never had any fade issues, even at COTA, in a near 4000lb car with a generally crappy brake design and cooling. Not going slow either... They are a good value compared to other options, about 2/3 price of PFC. I don't think they make them for the GT4 sizes. I'd probably give them a try on the GT4 if they made the right size, assuming the same value advantage. The DTC70 is the only hawk worth touching though...I will agree with that. TOo many students showing up with sporty hawk street pads...danger to society.

They have two great qualities IMO, 1) They are a very consistent friction w/r to temp. So you interact with them the same way lap after lap. 2) They seem to be nice to rotors relative to PFC. One thing I didn't like about them was until the rotors were bedded in with the pads material they were loud as hell on the street, worst I've ever experienced.

I did see this difference, but when I looked up the Ferodo parts catalog from 2016 they provided the average over the range. I understand that chart shows a higher value, but the printed document says the value (I was always told to trust the writing). Ferodo Racing Catalog - please refer to PDF page 7 and the description for DS1.11

I just finished installing Ferodo DS1.11 pads and tried to do some bedding on my local roads. Yes, Very loud, make PFC 08 sound quiet. I'm sure I'm not completely bedded. For those installing your own brake bracket and caliper studs I have a little info. Screw in the bracket studs until about 10 mm of threaded stud remains. The 62 mm caliper stud is for the front, the 85 mm stud is for the rear. I figured big caliper, long stud. Wrong, and fortunately I checked before the Loc-Tite set. Regarding Loc-Tite, Tarett doesn't send enough with the kit. Buy a tube of Blue before you start install.
