I'm guessing the autozone pads would have a low upper limit to their operating heat range. Once you exceed it, the pads would either fade badly or start to wear very fast.

That happened with some Porterfield R4S pads I used during my first track event with the Evo. They lasted less than two track session at Road America. Down to the backing plates in about 30 minutes of track use. Exceeded the designed heat range, I guess.

You may not have to pay $300 for pads if you improve the performance of the rest of your braking system. Put some effort and resources into the cooling. Rotor quality is also important. On the Evo, I've only had experience with the stock Brembo rotors and BAER Eradispeeds. The latter definitely work better, cooling-wise. I'm on my second set of BAER rotor rings now.

Please don't take offence, but what you are interpreting as others having more stopping power may actually be better braking technique on their part. I don't know how much track experience you have had.

 

i have PF rotors and i have used Ferodo ds2500, Endless CCX, PMU level max 900.
So far to my liking are Endless CCX and PMU level max 900. all of those pads people been telling me they are noisy, and i got 9 track days with my evo and so far no noise. Maybe cause i reuse all the stock sheems and clean them well/grease.

 

PF97 or PF01

 

never said anything about PF pads

 

I just ordered the PFC 01's all around. I'll report back in a few weeks on them for those interested.

Thanks for the help Drew & Dan!

 

^ I'll be curious to hear your results, Boomn.

Andrew, which Pagid Yellow compound did Dan run with the RA-1's?

I have tried using PF97 pads in the front and DS2500 pads in the rear. And I am happy with the combo, it works for me. Little to no pad wear in the front compared to the DS2500s I was using after similar track days. Actually it was hotter outside when I was using the PF97s.

The issue is not the coefficient of friction more than it is quicker pad deterioration due to over heating. The fronts see way more heat than the rear and I know Ferodo DS2500s are not up to the task of repeatedly stopping an EVO from high speeds for a long session (at least on stock rotors). Since braking is more tire and weight dependant, you'll need pads that can withstand more heat due to stickier tires.

 

I'm running PF01s on my Evo front and rear and love the combo...I may try the new 05s for the front after I burn up my stock of 01s. Todays max front brake temps while qualifying at the Glen were 254 degrees C on the face of the caliper and 800+ C on the edge of the rotor...so they get a little warm

 

I have yet to try the DTC70's but right now with my Project My level Max 900, I cant do more than 6 -7 laps or I overheat my fluid (127mph in the straight). If I could find a pad that holds better temps and abuse that would be awesome. I do use my Level Max 900 everyday in my car, and love the stopping power, but damn they are damned hot!

 

Yeah you need better pads and fluid for the track. I have had vibration problems with the DTC70s, but others love them. SRF brake fluid, titanium backing plates and a brake duct kit in addition to the better pads will help keep things in check. Good luck

 

Well right now I use titanium backing plates, the Mitsubishi OEM break guides, and use Project Mu fluid, Im still searching and maybe will try the Ferrodo's or the Hawk's we'll see, I just dont want to boil or overheat anything else!!! I think I should do some custom air ducts.

 

Here is the brake duct kit I use and the only SCCA approved setup: http://www.amsperformance.com/store/...oducts_id=1202 Easy Install with noticable results. Good Luck!

 

Ive been using the PF97's in the front...im happy with them. I also use them as my DD, so i drive to events and back with them...but other than that i dont do that much DD with them. Ive done 10 events with them thus far...5 track days, 1 Time attack, and 4 NASA TT events. So its not like im using them for a relaxing Sunday drive.

 

I just thought I'd second the second post in the thread;

The Raybestos ST-43.

Great pad, no fade, have run with 245/45 Hoosier Cup tires and 235/45 RA-1s on my old car.

On my old car I disabled ABS, my EVO9 RS has no ABS, key factor for me, easy modulation under threshold braking. My Hawk street pads are less manageable.
