+1 on the PF01/PF97 combo and I run big blacks up front. Tried the Ferodo 2500 but there was fade when hot. Swapped those out way before they wore out.

Porterfield R4. Noisier than a city bus, but medium initial bite and very linear pedal effort vs braking force, so they are very easy to modulate. Strong enough to lock the brakes on my 85.5 at 200kph for as many laps as I could do.

I have Hawk Blues currently and I have not yet tried them, but from what people say they're a great pad. I have run PF97s and they're great -- really like them a lot, though the dust is pretty ridiculous.

The Porterfield R4 is decent as well, though last time i ran them (I was totally stock 951 brakes at the time) I managed to overheat them. No experience with them after I installed my ducting or different wheels.

Ok so I've been running PF97s at all 4 corners and they DO seem to chew up rotors... especially the fronts.

Did a quick Google search - seems like the advantage of the PF01 is less rotor wear, at the cost of burning through the pads faster.

Those of you running the 01s up front - did you start off with 97's all the way around and switch? Is the improvement that substantial?

Sadly, pads are more expensive than rotors!

Depends on which rotors you use. I've read some guys who've switched to PFC rotors get better life but that might be psychosomatic after spending the extra money. I found that the oem X drilled rotors crack up very quickly with these more aggressive carbon metallic pads too.

I have PF 97 front and rear but haven't used them yet after cooking a few sets of Porterfield R4. The PF pads are supposedly bedded at the factory - the problem I have with this idea is that part of bedding in is that you are supposed to get a thin film of brake compound transferred (evenly) on the rotor face in the bedding process and that obviously can't be accomplished until the pads are used. My concern about the PF01 and PF06 as well as DTC60 and 70 is that they might have too much bite for a non-ABS car and cause big lock-up / flat-spot events - any opinion on this?

A new PFC brake ROTOR does not require bedding IF they are installed with used PFC pads. All other combinations require bedding and it is always a good idea to bed in a set of pads and/ or rotors.

I've used PFC01's, Hawk DTC70's and Pagid Blacks. They all feel about the same. I used Hawk Blues back in the day, they can't hold a candle to either of the first three in performance, they're also very hard on rotors and make a ton of noise.

Pagid Blacks all round works great. Nice on track, some noise when cold on the street, but still ok bite.

I've been using PFC97s for several years and love them. My bedding procedure consists of a couple moderate braking events on the warm-up lap.

The cost of 97s is getting ridiculous for M030 front calipers so I tried Hawk DTC60s last year at a DE. Decent bite but harder to modulate. Also take a couple laps to come up to temp whereas the PFC take 1 braking zone.

I typically replace rotors due to heat/stress cracking before they wear out, so the aggressive

Edit - pads no longer available. Family member called me up in need.

Are the Hawk blues similar to the Pagid Blues?

I've used the Hawk Blues for years on a race car. Very good pad but I've cracked two rotors with them. Just switched to the Hawk DTC series. Using the DTC-60's on all 4 corners. Very controllable pad. Good stoping power but easy to modulate. I'm also trying regular rotors with them. Not slotted or drilled. My understanding is the new pad technology does not need slotted rotors to release the gasses.

I use Pagid Orange all around on my daily driven but heavily tracked '86 951. I have a stock engine and it is at full street weight + roll bar, so close to 3,000 lbs. I have never had fade issues with the Oranges, and they bite well and are predictable, even though they are supposedly older technology than the Blacks or Yellows. I have front brake cooling ducts and have stainless lines. I also drive the same pads on the street. They are very noisy and annoying, but they actually stop very well even when stone cold in my experience. I think that they make some dust as well, but the stock phone dial rims do not show much dust in any case.

I may consider stepping up to Blacks when I start running R-comp tires, but since I still run street tires on the track (many sets of Dunlop Direzza Z1 Star Spec, now Hankook Ventus RS3), I can easily lock up the wheels and flat spot tires if I am not careful with the Orange pads. They are expensive but well proven in my book, and the nice thing about the early non-S cars is that you can rotate brake pads!
