Been talking to Tim at circuitsupplies.com, very helpful guy.
Ferodo DS2500 pad is part number FCP646H.
Stevie, do you think it's a reasonable idea to edit your first post to include all the correct part numbers?

I've change my origin setup to 840 Brembo Caliper and I'm happy about this, fading isn't no more my problemDaveW said:I've just removed my Brembo calipers from the Bi-Turbo after a failed experiment and thought I'd share my findings here in case anyone was considering something similar.
Looking for cheaper ongoing maintenance, Bi-Turbo discs are €290 each, I decided to fit the 4-Pot Brembo calipers/324mm discs from the 840 with DS2500 pads. I ran the car for 2000kms with this setup but was never really happy with the pedal travel nor feel.
I replaced the master cylinder, checked the rear discs were not out of shape (piston kick back etc) and had the brake fluid changed and bled twice by MJF then by Phil Crouch. A pump of the brakes returned the pedal to the top indicating air in the system but it wasn't this. The conclusion is that these calipers are not matched to the E34 and will always have a spongey pedal with long travel.
I've just had Phil replace the original Bi-Turbo calipers with new discs and Mercedes S600 pads and the transformation is very good indeed. Hard pedal at the top of the travel.
So if you guys are thinking of spending upwards of £700 on BMW conversion parts, don't bother as it probably won't work. What's worse, I've just laid out to return to original spec and now have to ebay the other stuff ouich
