Hello John.

Of course I understand that people have certain personal subjective preferences. I have tried Ferodo, Pagid, Hawk, Cool Carbon, KFP. All race compounds.( highest grip compounds of each brand)

PFC gives the most braking power(shortest braking distance), least amount of pedal effort, easy to modulate, long pad wear and rotor wear. These are my personal experiences. I have not done any controlled scientific experiments.

The car is a 1987 951 with big red front calipers (with Factory 3.6 C2T rotors) and stock rears. It has Turbo Cup plastic/rubber air deflectors that mounts on the control arms. The car has Bilstein Turbo Cup coil over suspension. The engine is stock( upgraded to K26/8 turbocharger) except Vitesse Chip.

The car is driven regularly at Watkins Glen, Pocono, Lime Rock etc. I am basing my opinion based on having used all of the pads mentioned at the same tracks.

JCP911S,

Didn't know you replaced that soon. In that case, the economics are about the same as PFCs.

I agree with your philosphy: don't change what isn't broken... (I guess that's why I haven't tried anything other than PFCs)

 

BTW, PFC works fine cold as well.

Eugene.

 

I've never tried Pagid orange, only blue. But have use a lot of PFC97s on my 930.
They stop the car, dont need any special bedding procedure, and work well in cold hence street.
I'm very happy with the wear rate though I do need a set of rotors per season due to cracks on my cross drilled rotor.

 

John,

I also use the PFC 01 compound and will second Eugene's opinion. (I have a 993 with stock calipers) Absolutely fantastic pad. I will add, however, that I did need to bleed the fronts after a day before I started using Motul 600 fluid which goes toward what Larry had eluded to in his earlier post, weight and caliper size may play a role. Considering Eugene's weight (2600/2700 lbs I believe) and Big Red calipers, I totally believe heat is not at all an issue. Once I made the change to the Motul there has been no negative issues with heat and I get through a weekend without any trouble. Time will tell regarding seals and such as Larry mentioned.

The car currently weighs 2700 pounds. I had tracked the car at stock weight( 3000+) and with stock 87 951 front brakes (w/Turbo Cup air deflectors) for number of years using PFC 93 and had no heat related problems with Calipers, Seals, etc. However, S4/Big reds provide better heat dissipation due to the larger calipers and rotors. The S4/Big Red pads last longer as well due to its larger surface area.

As a side note,my understanding is that compounds 83, 93,( I think that the 83 and 93 for some applications are being phased out) 90, and 01 provide more braking power than 97.

Also use brake fluids with a high dry boiling point. 530 deg or higher

Brake cooling kits should help as well ( should you need it )

FWIW, Performance Friction points out in their brake bedding procedure, for new Porsche 'drilled' rotors, that they recommend 97 compound, as the 01 compound may lead to lock up and control issues. They don't mention that for new Performance Friction rotors or used brake rotors.

 

Bill,

FWIW in my experience, I have bedded in many sets of the 01 compound on new and old rotors with zero issues. I believe Eugene may concur with that although I am uncertain about how many sets of 01's he's bedded. I have found the bedded of new 01's identical to the bedding of 97's, 90's and 83's.

I vote for the PFCs. For me they do everything better. FWIW I was a Pagid diehard until my racing experiences proved me wrong.

I used pagid blacks on the front of my 968 and had warped rotors at the first event (4/04). I felt I bedded them in as described but still the problem. Most people have buildup on the rotor but I had the rotors turned (slightly) and they were out definately warped. I have since gone to the same rotor but had it slotted by paragon products and i now use PFC 97's and they work great with no issues. I have 6.5 DE days on them and they look great. I know of other people that have had problems with the blacks as well when in the past they loved them. Could there have been a quality problem? At this point I will continue with the 97's.
