Hey guys, new track driver here (second event on the 27th of April), on a set of Hawk HPS brakes which won't do it for me. Car is 2500lbs, makes 330whp, wears 245 RC-1 slicks. I was considering Carbotech XP12 front and XP10 rear pads, but someone told me about PFC (never heard of them before) and I was wondering what a similar pad would be that you may offer, and if you could PM me a quote. I have a 2004 Mazdaspeed with sport brakes. I would really really like to get something that is in stock, so that I don't have to do another track day on my HPS brakes in this car. Also, I drive the car as a weekend driver sometimes, typically 2-3,000 miles a year, so I'd like something that will be able to handle regular driving in warmer temps, spring/summer/fall. Other brake mods as follows

Singular Motorsports 2.5" ducts
SS lines
ATE Superblue

Thanks guys!

 

I really love my XP12/XP10 setup. But it seems like PFC is also a good option, never tried them as I run Carbotech since 2006 on different platform and applications..

 

With the Rc1 slicks we recommend the PFC 11 compound. Slotted rotors are highly recommended. the 11 compound has such a high torque range that the heat has been chewing up cheap parts store rotors. if the rotors are slotted that will prevent the rotors from contaminating the pads, and insure long service life.








I finally have a inside source at carbotech and know what they are doing and how pads compare.
carbotech orders it's friction material from an outside source. they take a big slab of material, CNC cut it into a pad shape and rivet it onto a backing plate. other manufactures bake the friction material on to the backing plate. they use a large press and high heat. the reason rivets are bad is because you have 5mm of rivet protruding into the friction material. this would make a 13mm pad (like a miata) behave like a 8mm pad. the life span of that pad is severely cut short. on corvettes we have experienced 3x times longer life out of a set of pfc compared to a carbo.

the performance of carbo vs pfc.

Bite carbo is going to engage ABS faster and lock tires mich more easily.

Torque the consistency of a PFC 11 is 4% change from 200*-1600* carbo over the same range like a xp10 or xp12 is 20% change over the same heat range.

Modulation should be about even when matched to the correct tire.

 

True for some but definitely not all of their pads. Pictures:

the dynalight pads are only 12mm including the backing plate. No way those would last 20 min with rivets.

 

??

The dynalite pads in those pictures don't have rivets.

 

right, that would be pointless to have 12mm pads with rivets. Figure backing plate takes up 4mm. 4-12=8mm of friction material, if it had rivets you would be in the 6-5mm range. Anyone can burn up that much friction material in a day if used heavily. Like i said they source the friction material, and pads like that it would be smart to source the the complete pad.

 

I know Cobalt uses rivets. They give up a bunch of useful material.

 

Really didn't want to run slotted rotors, and the links are for 98-01 and I have the sport suspension so larger brakes. How are they for street use as I had mentioned?

 

You're advising slotted rotors for these for hpde guys? Sounds excessive.

 

the parts store rotors can't keep up with the 11 compound. the cheap iron is so bad that it falls apart and packs up in the pad. slots stop it from falling apart. if your running a big grip tire like a 245 maxxis then you need to a just your braking system.

 

Do they come in the sport brake size?
Do you consider centric premium "budget" rotors?
How are they on street?
How is pad attached to backer?

Sorry for all the questions. If it's easier I can call and discuss for a few mins on phone let me know

 

sorry nuts here today. trying to get to everyone as best as we can.
-no
- centrics should be fine. watch out for the ones from world pack. they have a bad batch that are killing pads.
- it's a race pad so it's going to squeek, dust and your wife/gf will hate them. but they start working at 100* any day over 70* they will work fine. any day under 30* they need to get heated up first.
- the compound is molded to the backing plate.

call me any time. i'm at tracks Friday-Sunday. so call the OG racing super green cell phone. 770-880-7579. or you can call the main line during normal hours.

 

We have two cars here doing street stints between track days on PFC 01 / 11 compounds.

It is not your mom's street pad that never makes a peep of sound and never dusts, but what it is is pretty great; a true race pad with the best modulation and consistency of any pad I've driven on the track that can also be confidently driven on the street and stops even after cruising on the freeway and supercooling the brakes.

 

They sound great but I have sport brakes SK unfortunately there's not much I can do to adopt these PFC pads.

For those of us who can't fit these pads, can you recommend the next best alternative? Would carbotech be it or should I look at others too?

 

It continues to amaze me how great of a pad the 01/11 is on track and yet does not turn the car into a death machine on the street. I've left mine in 24/7, even when I want to drive the track car into work and I've had zero complaints. For a race pad the noise is minimal, far better than any Hawk I've street driven. Dust is expected with a pad like this, but I've been impressed how easily the wheels clean up. Even after sitting out in the rain, with a track days worth of dust, the wheels cleaned right up with no funky deposits or anything.

 

If it were me, I'd be changing my brake setup so that I could run the PFCs. A setup like the basic wilwood 11" front BBK and standard 1.8 rear brakes would still be a step up from the sport brakes, with faster pad swaps and cheaper rotor replacements to boot.

If sticking with the sport brakes, you'll have to look beyond the brands OG carries. That'd be a discussion for another section of the forum as opposed to OG's thread dedicated to PFC pads. Try here.

 

Congratulations to Ernie Ty Francis Jr. On his ta3 victory this weekend. Ernie and Breathless Performance run PFC brakes. 11 compound.

 

Good guys at Breathless and they sure know how to build and set up fast cars. They're very successful in their MX5 too. Besides the fact that they overnight every part they order from us, we like them

 

How old is he now? He still looks young. I remember when he was running in Spec Miata at Road Atlanta at age 13 or something.
