Yeah, I don't see how a high temp pad is going to work when you're driving home at night and barely using the brakes - this will mean your brakes are stone cold and thus outside of their intended operating temp.

What am I missing?

Perhaps Cobalt Friction pads are unique. They say they are. Stranger things have happened.

After one (maybe two) cold stops they retain enough heat to serve me extremely well for the duration of any trip. They came up to temp easily and FAST. Evidently faster than any other race pad.
I can only site 20K miles of driving with them.

They have worked since 2010, every time I needed them, especially panic stops. 20k miles on the fronts and the rears still good. I can only go by my experience. Sorry to disappoint everyones written in stone theories. Not my intention. I only wish there were someone else who ran the same pads on my set up. Never came across anyone.

I make certain ANY passenger is snugly buckled in. If I have to stomp on the brakes (cut off, etc) I would put an unbuckled person through the windshield.
I have never been happier.

I may regret not buying another set of Cobalt Friction. I already spent $900 on a set of Endless pads. Not going to lay out big bucks for yet another set. Not right now.

I may take Obioban's advice and buy the Brembo PERFORMANCE pads he is talking about. Later, when I can. I was not that impressed with the OEM Brembo pads that came with my GT set. I bought everything brand new in 2009. I bought some low dust ceramic pads that were even less impressive. I took those out after only a few weeks at the track when I put the Cobalts in permanently. Unfortunately, those pads have gone missing. But I did retain NIB a full set of Endless Racing Pads.

Inspite of my great experience with the pads, friction rings are way too darn expensive. The next set from Brembo I want will set me back over 1,100. Double that if I want the new Type lll rotors.
I attribute my low rotor life to my pads. I WILL switch. Probably next year. See next paragraph.

Obio, are you out there? Can you give me a part number for the pads that you referenced? I will bookmark those for the future when I get back my Federal Licenses (lapsed due to time off from extreme injury) and get my old job back making excellent bank. Currently making LOW bank and doing the best I can.

Ultimately, unless your brakes are complete garbage, stopping distances are 99% determined by tires and brake force distribution algorithms-- not brake pads. Brake pads can fool you into thinking the car is braking harder by having harder initial bite (especially if you're comparing to low dust pads, where bite always sucks), but unless you're comparing garbage to not garbage, stopping distances will be very similar.

The Brembo street pads I like are their custom formulated Ferodo FM1000s.

You can read about all their in house pad options here: https://www.racetechnologies.com/art...ke-pad-options

They also include the following disclaimer about not running track pads on the street on that list:
Quote:
*Denotes a "race only" pad.

-Running a "racing use only" pad on the street could produce excessive noise and dust.
-Disc wear could be accelerated if driven at cold temperatures or used in the incorrect temperature range.
-Racing pads are designed to work in specific temperature ranges so it is important to choose the desired compound for the correct environment the vehicle will be used in.
-Pad Compounds are run on a brake dynamometer over multiple brake applications (stops) to test the materials in a controlled environment for the most accurate data. Wear rates and temperatures can be influenced by car setup, grip levels, track layout/configuration and many other variables.

It makes them easier to swallow that they last forever-- I'm still on my 2nd set of them.

... hopefully one day FCP will start carrying them

I had no idea about these. Thanks again. Bookmarked for future purchase as soon as I get the rotors taken care of...
I can always keep the endless for future track sessions at Sebring or Daytona.
