The last few sets of pads I've had were Pagid Blues. I've been very happy with them, but they are expensive. Ferodos are usually a little cheaper, but how do they perform? I like the Pagid's cold bite, fade resistance and minimal noise. Ultimately I'd like something a little better when heat gets in them, however. I'm willing to sacrifice a little noise, rotor wear and maybe even cold bite for better max braking when hot. I've considered the Pagid Oranges, but fear that may be too much pad for my year-round driving in Colorado.
I have a stage III A4 with A8 brakes and track the car a few times every year. I have no interest in multiple pad sets simply for the fact that I'm lazy. And yes, I understand I will compromise with just one set of pads. TIA.

And cold, the Ferodo DS2500 is much better than the Pagid RS4-2 Blue. The Pagid RS4-4 Orange will squeal badly on the street. See also the <a href="http://forums.audiworld.com/a8/msgs/81590.phtml">10 Pad Comparison</a>.
The Alcon H-Type and B-Type calipers are 2-piece, but they're 4-piston. I'm only aware of the various Alcon monobloc 6-piston calipers (which don't all take the same pad).

...i really want part number for the monobloc 6 caliper, but most companies don't have a cut yet for it.
But it's the same pad as the 6 piston 2 piece caliper with a notch in each bottom corner.
The caliper looks like yours, but the twopiece version (same gold anodized type color).
But better still, if Ferodo has a part number for the Alcon Monoblock 6 piston.
Thanks for any help, just planning my next pad purchase.

FRP 3003H - DS2500 compound
FRP 3003R - DS3000 compound (their most popular race compound)
FRP 3003L - DS3000 Plus compound
FRP 3003E - DS3000 Endurance compound
But ... The backing plate of the Alcon TA-6 pad is 6" wide. I believe the Alcon 6-pot used by Stasis takes a pad with a 6-3/8" wide backing plate. What pad are you using now? I would think that a Ferodo dealer would be able to cross-reference a Pagid number, for example, to the corresponding Ferodo number.
Also with probably any caliper, the hat also determines what the maximum height of the pad material itself can be. With my Alcon TA-6 for example,
Ferodo FRP 3000 = 1.890"
Stasis Mono6 spec = 2.00"
Pagid 1903 = 2.072"
Ferodo FRP 3003 = 2.102"
TA-6 pad spec = 2.125"
Cobalt Friction Vspec = 2.140 (no numbers on the pad)
- The Ferodo FRP 3000 leaves a rather large unswept area with my TA-6, the rusty area visible in the rotor pic.
- The Pagid 1903 fits fine.
- The Ferodo FRP 3003 is just about perfect. The pad compound itself uses 99.9% of the swept area between the hat and the edge of the rotor. I have to grind the backing plate flush with the pad to avoid the backing plate hitting the hat when the pad is worn.
- The Cobalt Friction pad wouldn't fit at all, the pad hit the hat.
You just finalized my decision to get the Ferodos next time. I had seen that 10 pad post before. Oustanding info. Would you say the 2500 is as good or better than the Pagid Blue when hot?

... forget the Pagid Blue.
I had a near new set of Pagid Blue's almost totally evaporate in one 30 minute session at Mid-Ohio. I wish I had brought a camera, but the rotor looked like someone had used a putty knife to smear molten metal onto it. The molten metal was what was left after the semi-metallic pad (all of it) evaporated, and it totally coated the rotor. I used the Ferodo DS3000 to clean the rotor during later sessions :-)
Since then I've never used street pads on the track, but I know several A8 drivers who use the Ferodo DS2500 street and track. I'd classify them as beginner or intermediate drivers, but they haven't had fade problems.

I'm guessing the DS2500 should suit my needs well. I've never had a problem with the Pagid Blues on the track. Maybe some VERY light fade...maybe. That should give you some idea of where I'm at.

Finally figured out turns 9-12 at Grattan and ended up with much greater speed at the end on the straight becuase of the speed I even braked really early before the cones they put out and still ran out of track about 5-10 feet before the sand I managed to slide the car sideways at 60 mph through turn 1. Still had pedal pressure just no stopping power.

Either the Pagid RS14 Black or Ferodo DS3000 in the front.
Whichever you use in the front, you'll want the DS3000 in the rear (the Pagid RS14 isn't available for our rear calipers). Now that you've reached the limit of the DS2500, you'll want to make sure the rear brakes are doing their share of the work :-)
