Brake Pad Thread, for 345mm M5 & CSi floating disks and 324mm e32 4-pot calipers

Member GoneAgain was right, the pads are the SAME! BMW uses two different partnumbers, but I think that is because each uses a different friction material, Textar 4056 on the M5 & CSi vs. Textar 476 on the 750i.

Dimensions: 99.3 x 57.7 x 18mm









Above pics show the Pagid RS42 pad supplied by the e34 Heritage Center compared to the Ate 4-pot e32 caliper and it's OEM T476 pad.

Browsing the web this, the universal WVA 20309 number and the now known applications show some interesting availabilities:

-Ferodo lists no applications for the '95 M5, but does show DS2500 for the 850CSi of which we all know is the same.
-EBC lists RedStuff (DP3886C) pads for all above applications, but also DP31032C pads, which according to their catalog are 121x71x17mm. It seems to me those will not fit these applications, but are correct for the Brembo 4-pots used on 840i/Ci that also use the 324x30 discs. (Hawk also has 3 compounds for the Brembo calipers using their HB-181 number)

Shortlist of available performance pads so far for Ate 4-pot calipers:

Pagid RS42 (made to special order by batch, PM member Konstantin for availability)
Ferodo DS2500: frt pad is part number FCP646H(rear FDS 857)
EBC RedStuff: DP 3886C (rear DP3871C)

Anyone know of others?

I take it that these pads work well with the standard disc? Also with the disc being a floating type?!

These pads will work much better than the Textar chocolate poppadoms BMW sell.
The std pads are an organic based compound.
The other pads have a carbon / kevlar binding that makes them more resitant to chunking & delamination.

The floating discs are good items but will eventually succumb to repeated hard use.
You can extend lifespan by respecting your brakes & cooling them.

The biggest mistakes that can be made with aftermarket pads is to slap them in after using conventional pads on the same disc.
The discs will have traces of debris from the oe pads that will affect the new pads face & destroy the breaking in process by causing local hot & cold spots on the clamp face of the pad.
The disc should be skimmed or degreased, then buffed with a scotchbrite bar to remove contamination.

Its just prep work but it needs to be considered.

If they are recommended by the E34 Testing Center at the Nürburgring Meuspath, I'll take their judgement any day..


I need those pads...Need the rotors first though....Kidney, anyone?

Another pad is the TWR/Lucas part number GDB1161. They are for the e32 4 piston calipers. Does anyone know where I can purchase a spare piston for ATE calipers?. I'm trying to rebuild some e32 4 piston brakes and I need a new piston because it has pit marks in it. I'm pretty sure carbonpanther (in the USA) can sell these types of pads also. Thats what I was reading over on bimmerforums a while ago.

Same here .....if I were to upgrade the pads on the LE , I would renew the discs at the same time .......

I think I'll see how late TK is braking at Bedford later this month ( as he has fitted this lot ) before deciding .

Great thread Stevie.......the more time I spend on this forum , the emptier my pockets feel ...

Is this a high performance pad or just standard replacement?

Good work Stevie.

But Im pretty sure that ferodo number is wrong. 95% sure I ordered those when the calipers were fitted, but had to send them back. they are off the single piston caliper on the 750iL.
