I got my 2000 s4 for about half a year and it got Stoptech big brakes installed just wondering would that be possible to get pads other then Stoptech dealers? Where and what do you guys recommend for street use with less dust, I hate BRAKE DUST!!!! Thank you!

The StopTech ST-40 caliper is designed to use a pad from various Porsche models including the 944 Turbo, 1991-1994 911 series, 1992 968 and 1986-1991 928.

Numerous manufacturers make different compounds from street to full race applications for this pad shape. The Friction Materials Standards Institute (FMSI) establishes a numbering system for pad shapes in virtually every vehicle sold in North America so that cross referencing the various OE part numbers can be vastly simplified. Some pad manufacturers have a cross reference between their numbering system and the FMSI number, but others still do not provide such a tool.

The FMSI number for the pad used in the StopTech ST-40 caliper is D372.

Over the years, Porsche has consolidated certain pads with slightly different backing plate shapes. Though these pads that Porsche consolidated will all fit in a Porsche caliper, they will NOT all work in the ST-40 due to the tighter tolerances of our bridge and pad retaining system. Other FMSI numbers used for similar pads are D447 and D609. While this reference may work with some pad suppliers, only a D372 pad is assured of fitting the StopTech ST-40 caliper.

Here is a list of manufacturer's part numbers that will fit our caliper (X denotes pad compound):

Axxis: DB439
EBC: DPX767 (uses D447 as FMSI cross reference)
Ferodo Race Pads: FCP560
Ferodo Street Pads: FDB560
Hawk Performance: HB141X.650
Mintex: MDB1456
Pagid: U1204
Performance Friction: 0447.XX.17.44
Porterfield: APS-4
Raybestos Race Pad: R609
SBA: 3041.X.X

Note the number represents the SHAPE of the pad, NOT the compound. You will need to check with each individual manufacturer for the complete p/n of a certain compound, but the numbers above will be part of each. The letter "X" represents the portion of the number you'll need to fill in for the compound.

Also note, Porsche has consolidated all their pads sold through the dealerships to a number that will NOT fit in our caliper. Strange as it may seem, the only place you can't get a pad for our ST-40 caliper is from a Porsche dealer.

Thank you very much! Very informative got to print this out.

can be found on stoptechs site. Also try to use the subject line. It makes reading easier.

These are the pads that ship with the kits and are sufficient for street use.

the ultimates are to noisy and dusty for daily driving.

I would not.

I run them for the same reason. I was cleaning my wheels almost daily with the ultimates.

Too dusty and require re-bedding every few hundred miles.

and were great for the first part of their life. Now that they're nearing the end, they aren't behaving predictably.

So, take that FWIW
