OG Racing: PFC race pads.
 

My set of PFC 01's are on the way. Can't wait, thanks Johnny!

You may also want to list the options for the dynalite caliper since it's perhaps the most common among BBKs.

-Ryan

Is the PF11 the replacement for the PF01?

+1 on Dynalite fitment. I think some are using Dynapro as well, but I don't know if the pads are different.

the PFC 11 is the replacement for the 01. we should see the compound in the Circle track pad shapes in the next year or so. lefthanders take a real long time with change. We got to break them in slow. FYI the diffrence between the 11 and 01 is 6% better in every way. higher tq, better modulation.


The PFC hierarchy
(Old compound/new compound) listed from high tq to low tq.

07/13 very high Tq pads. unless you got an old Indy car (huge downforce) or drastically under sized rotor you don't want this.
01/11 GT compound #1 choice of pro teams.
08/xx GT endurance - high tq.
06/12 GT endurance 4% less Tq then gt compound but 10-15% longer life.
97/14 Low traction. rally/dirt. small street tire.

you don't want to put too high of a TQ pad on your application or modulation and braking feel will suffer.

PFC rotors vs brembo.

So no 06 compound for the dynalites? Bummer. I'm thinking the 11's are a bit too aggressive for me. will be running federal RSR's, eventually going to an RS3, on a 949 BBK.

for the federals tires go with the 97 compound. it will give you the modulation your looking for, and won't over power the tire.

Will that still be sufficient when I step up to an RS3 or rival later? Thanks for the info, I hope this is useful info for others too.

got it listed above. the 01 compound is good choice for rs3 and greater.

Ok. So 97's while I'm on RSR's, then step up to the 01 after that.

Thank you sir.

I'm running the 01 in my Dynalite caliper on BFG Rivals and Maxxis RC-1. Good modulation for either tire, I don't feel like it overpowers the Rivals.

-Ryan

Pardon me if I'm just missing something. How do these fare for dual-duty pads? Are they going to be horrible on the street? I'll likely start with the 97's which I'd expect would be fine for dual duty, but what about the 01's?

I know some folks have had some difficulty bedding the Carbotech XP10s on the 11.75" rotos. Any difficulty here?

Can you drive them to the track, yes.

The temperature range is so huge they don't need to "heat up" to start working. Any day over 50* you won't have any issue.

Double duty? i would advise not using any race pads on a daily driver. for one reason.

ALL Race pads have a very high iron content (100% of race pads, every manufacture, despite what they might tell you). every one knows iron rusts. The brake dust on your wheels that comes from Race pads will rust. So your very nice custom ccw's that are very expensive, if you get caught in the rain, the wheels will rust. You will not be able to remove the rust without sanding. for that one reason i would switch them out. if you don't care about dirty wheels then ignore me.

My NB has 01 pads that stay in the caliper. I drive it 3000 miles a season going to and from events. the pfc 01 will squeak. to that i say, my whole car is obnoxious what's one more loud noise...

Haha... thanks for that input.

The Miata will not be a daily, I misspoke there. But it WILL be street driven, on weekends, and probably to work once in a while. It sounds like you've answered my question though -- basic street driving is still fine, but it's not a daily pad, which makes sense.

Thanks for the help. I'm obviously not very familiar with PFC (and in the early stages of learning about pads in general) so this is very helpful for me.

What about powder coated wheels? Will the brake dust rust those? Or does the brake dust itself rust?

the dust rusts. the aluminum itself won't rust. once it gets rust it's a real pita to remove. elbow geese won't cut it. the rust embeds itself into the aluminum, paint, power coat, ect.. .

OG pays me to answer your questions. let me know if you have any more. but do try and post it into this thread https://www.miataturbo.net/general-m...estions-81577/

try to get a collection going.

My PFC 01's don't squeak on my 11.75" V8R/949 kit.

they are not as bad as other manufactures. i say they squeak so if they do make noise once in a while customers aren't upset. It a good habit to under promise and over deliver.

If we do care about the dust, does PFC have a street pad that can be alternated with the 97's on the same rotors?

Wait...what? How? Where? Inside the gate? Have seats there? Helmets?

Subscribed for dynalite pad info.

7752 backing plate, 01 and 97 compounds available. 7752 fits the Dynapro 4-pot as well.

our seat selections is best at the sterling location. the inventory at NJ is constantly changing. NJ location will keep helmets and suits for you to try out.

The 2015 Porsche cup car brake kit.

Bumping this with a question, I'm ordering pads this week.

Planning on PFC 97 on the front (949 11.75 BBK), but what do I run on the rear? I've got sport rear brakes. I don't see a fitment listed above for the sport rears.

Thanks in advance!

Something I just found out is you can run a non sports brake caliper on a sports brake bracket. And its what's recommended in conjunction with the BBK if you don't have big aero.

this.

there is nothing available (padgid or PFC) for sport calipers. many people have been modifying 1.8l rear pads to fit.

An on topic question what tires are you using? i'm a little worried about the 97 compound selection.

Oops. That was supposed to he a question. I wanted to hear your thoughts on it.

He's running like federal 959s or something? Street tire.

On running aero? It's all about balance high speed vs low speed.
for an extreme example, when the DP teams they still had iron rotors. carbon carbon came in after the grand-am ALMS merger. a DP car around Daytona going into turn 1 (200mph- 70mph) had so much down-force that the drivers could stab the brakes with both feet and they couldn't lock the tire. As the car got closer to the apex the downforce would decrease, the tires coefficient of friction would decrease, the driver has to decrease his pedal force to stop the tires from locking up. The trick was balancing out a system that could slow the car fast enough into turn 1 ( a big passing zone) but still have enough usable friction to have good modulation in the slower turns. The difference between our cars and a DP is DP’s have the advantage of cash. That cash pays for wind tunnel testing. We don’t have that cash to achieve the perfect aero balance On our Miata’s the trend is big wings. so our aero balance is going to be heavy in the rear. if you’re on a very fast track that has a majority 60+ mph braking zones I could start recommending higher Tq pad in the rear to take advantage of the down-force. the down side of a set up like this. is when the aero stops being effective (under 60 mph) your braking balance is going to shift to the rear. so to recommend a brake set up I would need to see how your aero is balanced, what track your running, and what you’re looking for as far as balance.

So without aero using the sport calipers over torques the rear brakes? So using the normal caliper with sport rotors is better for balance?

I was planning on the 97 compound per your recommendation in this thread. These are the tires I'm running: Federal Tyres - UHP - 595RS-R

My understanding is that they're supposed to be comparable to an RS3 or Rival in terms of grip, but I don't really know.

For running the regular 1.8 calipers on sport rotors there's some other adapter needed, no?

I'm not trying to clutter this thread, this is just regarded as the hot brake setup so it'd be good to know your recommended PFC setup. Curly recommended DTC 60s front and DTC 30s rear on these brakes.

Oh, and as of now I'm not running any aero. Stock front undertray and nb1 sport front lip which probably doesn't do anything.

From what I've gathered recently you can use your sport brake bracket on the 1.8 caliper to put it on sport rotors.

it all depends on your aero balance.

the debate over what calipers to use comes down to “it depends”. We are trying to find a dynamic balance under braking. A wide spread solution that many Miata’s are finding a good balance is with a aftermarket prop valve, a 11.75” Front brake kit (V8 roadsters for example), and the sport rotor Rear w/spacing out the factory 1.8 caliper. This combo has been found to provide good balance with most racers while keeping the parking brake. The sport caliper has a 1.375” piston and the 1.8 rear caliper has a 1.25” piston. The area of the pistons are 1.23^2” for the base and 1.48^2” for the sport caliper. A difference of 18.5% larger to the sport caliper. As there are only 3 ways to affect brake Tq on a given axle (hydraulic advantage, Pad compound, rotor Diameter) and changing piston size falls under hydraulic advantage. the change from 1.8 caliper to a sport caliper will net an increase in rear brake torque. Is this a good thing? If you had an trail braking happy rear end, no. This would make the problem worse. Adding a big rear wing should keep the rear in check and allow you to run more rear tq. Running a sport caliper is an option to add some extra Tq to the rear of the car, just take time to consider if you need the extra tq.

On my own set up my stats are as follows.
2400lbs, 450ish hp, afco shocks 550f/440r, 11.75" F, the 1.8l caliper/ sport rotor R. I can easily obtain a smooth trail braking condition. That might change as I intend to raise the wing 12” and add singular endplates. IMO if a parking brake wasn't needed I would rather have the V8roadsters 11.75” kit on all 4 corners. to bring balance is would choke down the prop valve. It makes bringing spars to the track that much easier and has considerably longer life.

I saw your email thank you for the inquiry.

We are currently backordered on the low tq option pads. Miata turbo has been eating them up. You can keep running the hawks as we wait for a new low tq pad to be sent. Or you can try the 11 compounds. The extra tq means you won’t be able to jam on the brakes as much as pro would. ( I jump the brakes like I’m kicking a football) you’ll need to take it easy but it wouldn't call it uncontrollable.

i street drive 01 compound pads. they start working at a very low temperature. so no need to worry about panic stops. it is a race pad so do take into consideration if you get caught in the rain. if you do wash the wheels as fast as you can. or follow my lead keep a set of black wheels for your track days. nobody notices if black wheels are dirty.

And please ask all the questions you can. I Try to help everyone I can. That’s what I’m here for. + It’s free bumps. :)

First half of that correct, second half is backwards. Moving to 1.8 caliper from sport caliper is 18.5% reduction in torque. ;)

DOHH fixing now :giggle:

Congratulations to Ryan Passey #thepass.
On his win over the weekend running RTA unlimited class.

He was running pfc 01 compound.

Shit son, winning GTA unlimited? Thats badass.

RTA, you mean? :)
congrats to Ryan

:facepalm: woops

Thanks Johnny!

For Saturday practice I co-drove the car with Sean. (Back-to-back sessions in 100* ambient heat all day long and the car didn't miss a beat, but that's a whole 'nother story). I've been telling him he HAS to try these PFC pads. I've been raving about them and he was skeptical. First session he comes back in and says these will be his next set of pads. Enough said :)

-Ryan

Johnny, do I need to switch rotors when switching pads with these? Currently running stoptechs

No. You shouldn't need to swap rotors for the sake of the pad compound. If they are worn and grooved you should be swapping them because of rotor wear, but other than that, no.

So I can go back and forth and have one set for track and one for street?

i couldn't say it any better.

yep, you can swap them without worries.

Just to clarify the whole sport rear caliper thing.

The bracket, or carrier, you use, is what determines whether you use a sport pad, or a standard 1.8 pad. If you want to use the standard 1.8 pads, you'll need to buy something like this: Miata Sport rear rotor Kit , so as to use the standard 1.8 carrier (bracket) on the larger sport rotors.

I currently use the sport caliper on the standard rotor and standard pads (along with the standard front brakes), because I wanted more rear brake bias. I found that the car was very prone to locking up in the wet under hard braking (not good in emergency stops), and I didn't want to wreck sliding through a red light, because I got caught on a yellow.
After back to back testing, the fronts still lock up before the rears, I stop in a shorter distance in the dry, and much shorter in the wet, without fear of locking up easily.

Mind you, I daily drive this car on parts store ceramic pads. Were I to be on stickier tires and upgrade to more aggressive pad compounds, that bias may change, but everyone's setup/driving style is a little different, and requires different needs.
I just wanted to mention the above.

Wut. This shit is getting confusing. So Sport Bracket with rear standard caliper will need sport pads?

For the most part, yes.

Whether you can modify the standard pads to fit, I don't know. You may run into issues with the hardware. But from everything I've read when I was looking into swapping parts, the carriers determine which pads you use.

Not going to lie, I totally thought these were snake oil pads when Ryan first talked about them. After running back to back sessions in his car and experiencing how much win they are...I'm a believer. I can't see myself running anything else now...they are super smooth and control on application and release. At this point the PFC pads are hands down the best pads I've tried.

All,
We (OG Racing) managed to snag the last PFC 0636.97 pads that will be made. we only have 3 in stock. It will be some time until we have another low TQ option for the rear of 1.8l miatas, as we wait for PFC to replace the 97 compound with the 14 compound.


http://www.ogracing.com/media/catalo...0636_web_1.jpg

97 Compound.
Low Tq option. Best for low traction events. Example Dirt, rally cross, or low Grip tires. Very easy modulation, good flat Torque curve threw-out heat range. 10% less Tq then PFC 11 compound. suggested for the following tires. toyo R1R, Bridgestone RE-11A, Dunlpo star specs, Falken 615.

if you want to have one of the last 3 97 compounds you will need to email me. Johnny@ogracing.com.

monday... ughh no updates just bumping.

Got more updates. NASA SE June Jam @Road Atlanta - Took home the nasa TTU (unlimited class) win on Sunday. Saturday i came in 2nd. i was running the PFC 01 compound on 11.75" pfc rotors, rear where sport good win racing "Sport rotors" with PFC 06 compound.
