Which PF Pads compound? 01 or 08?

[Gibbo205]

Hi there

911 has 08 compound which are superb and seem to last forever. M3 has 01 compound which also seem amazing.

The M3 needs new pads, do I go 01 or 08, anyone tried both in their GT3, how did they differ?

If it matters car has PF front and rear two piece disc.

Have you considered Endless pads Gibbo? Probably the best track pad available and work well from cold. Expensive, but they last an age!

Heard of them and suspect they are excellent but as the saying goes I am very happy with the PF pads and disc, plus Id rather match PF pads to PF disc. Just interested mainly in feedback from those who have tried both the 01 and 08 compounds.

Endless MX72 compound are very good pads but last for ages? I don't call 6 trackdays "ages". If money was literally no object, then I'd use them, but £150 / day just on front pads is too rich for me.

I've tried 97, 01, 06 & 08 PF compounds with PF discs. 01 is very aggressive "race" compound (it takes a bit of heat to get it working & it squeals like a stuck pig on the road); it will also cover both the wheels & sides of the car with a metallic dust that's a bugger to get off. 08 is more of an "endurance" compound that probably doesn't have quite the stopping abilities of either the Endless or the PF 01 compounds, it is far more road friendly (by which I mean they are silent, will work from nearly cold & don't produce corrosive dust &/or wear the discs too aggressively) & the pads themselves wear well; I run them down to 2-3mm of friction material, which you can't do with Endless or Pagid.


I have tried virtually everything over 135 trackdays & I'm now using PF 08 all round on floating 350mm Alcon rear discs & floating 380mm race Brembos up front. I'm very happy with this combo.

ETA: If I had to criticise PF pads, it's that the steel backing plate deforms under the load from the caliper pistons & makes the centre of the disc surface wear faster than the inside & outside edges. Don't seem to get that with Endless.

hi Gibbo & Nick

I'm just about to try Carbone Lorraine RC6E pads for the Italian trackday tour which is at the end of the month.. Always used Pagid with Alcon rotors until now but just fancied a change.. We use the CL pads on all our race cars so they come highly recommended and are more reasonably priced than the very expensive RS29's.. will let you know how they perform as I try to keep up with Nicks monster round Monza

Nick, aren't you just running regular type brembo upgrade discs or have you upgraded again?

Hi Neil

I'm running 380mm Brembo floating race discs which are fitted to custom-made bells - as you know, 380mm was never an option on the 996 and won't fit under many 18" wheels. They should just about last until after the Italian trip when I will be replacing them with the endurance version of the same disc. These are the same thickness but have smaller central vanes & therefore more metal in disc thickness if you see what I mean.

This is what they looked like when they were new:




Have you tried the new RSL pads yet? A mate is trialling them at the moment but hasn't done enough with them yet to see how they hold up compared with the RS29

Endless by name but not by nature. I have endless down to about 3mm and they work great but are basically "ended" now. Lasted a tad longer than prevous rs29 but only a a tad.

How much and where for the Carbon Lorraine? Can you get them in both GT3 back plate sizes?

ETA. Will probably go PF06 as these have been brilliant on the rear for me so far.

[bobsan]

another shout for Carbone Lorraine RC6E, excellent pad, used on other cars and mighty impressed.

currently on PF 08 for the porker and very happy with them though suspect CL are equally capable, no more Pagid until they catch up in compound and price structure.

Nick,
Why the custom bell and not the Brembo bell?
And why Alcon on the rear and Brembo on the front?

I thought "endless" referred to the fact that they don't fade ?

Hi Dan hope your well...

I got a full set (front & rear) for less than the price of a front set of RS29's..

Pretty sure they are available in all sizes.

Cool, will give a call

My mistake, i thought they lasted forever, trading standards anyone?

Hi Jack

Alcon are a direct fit onto the rear PCCB bells. The PF version require you to purchase their bells if you want a handbrake & they cost a fortune.

You need to make custom bells because nobody makes a 380mm brake kit for the 996. The disc offset is different on the 997.2 & the CL fitment makes it incompatible anyway so you can't just slap those on. Went Brembo because I could & being race parts they came in at a better price than Alcons which would have only been 362mm anyway.

nick,

yeah that was the picture i had remembered seeing. the metallurgy on the rotor itself doesnt look like the race brembo rotors i am used to using/seeing hence the question as to whether you had abandoned the pictured ones already and upgraded again since you hadnt seemed to have fitted them that long ago.

whats your thinking behind using a 380mm setup? dont you just limit your 18" wheel choices dramatically and have to lug around extra weight?

the brembo racing hats use a different mounting style to your hat. it might be worth considering a wholesale change across if you plan on keeping the car for a while. the mounting style you are running there (as as offered by most stuff) doesnt last much longer than 3 rotor swaps. the rotor isnt fully floating and it elongates the holes in the hat over time. the brembo race stuff uses a heavy duty type mounting that leaves the rotor fully floating and as such the hat lasts almost forever. it rattles like crazy but works very well.
the 997 cup uses a 380mm front rotor and brembo racing offer a rotor for this. you should be able to just mount this rotor to the 996 cup/RSR brembo racing hat and get going if you need to keep a 380mm front. the 350mm/330mm sizes usually come in around £1100 a corner (so £4400 for the whole car). the 380mm size is usually about £150-£200 more.

They were fitted in July last year. I'm using 2 (soon to be 3) types of wheel. I have OZ Alleggerita 18" with Dunlop slicks, 2 sets of 19" OZ Ultraleggera , 1 set with Michelin Supersport & another with Cups, and I have a set of 3-piece forged 18" Cargraphic which will be fitted with Dunlop wets for next year. What I lose in extra disc weight I gain back in stopping power, longevity + the OZ wheels are very light compared to most alternatives.

Yes, I think I know the hat/disc combo you mean. I think that there's a problem using those unless you are going to go full motorsport hubs with the CL BBS race wheels. My recollection is that the caliper / disc sits a lot further inboard from where they do on the road car. Changing the rears for a race setup also means you lose the handbrake.

At that point you are getting into the dangerous (for me) territory of convincing yourself that a Cup car makes more sense

[Brummmie]

Just so you guys know the pad numbers for these in Carbone Lorraine/CL Brakes, are 4075 and 4050, RC6E (endurance) is the equivalent to RS29 (Pagid), and RC6 (standard race) is a like an Rs5.

Thanks Paul.

I've been really impressed with the PFC08.

They have a great bite, they're not too noisy on the roads (they do squeak a bit after getting hot, but a few miles of road use quieten down again).

The bite is not as sharp as the PFC01, but its full of confidence, and consistent.

With a set of 4 for ~700 EUR, compared to Endless, where just fronts were about that much, I think they're great value too.
