Brake pads options for 370mm Brembo 4 pots

[Slickric21]

Hi all,

Im having a nightmare trying to find the specific part numbers for replacement pads on my R ST that comes with the 370mm disc and Brembo 4pot calipers.

Ideally I’d like Ferrodo DS Performance or DS2500 but I don’t know which ones to get ? Eg the specific part number

Alternatively open to other ideas, but don’t want the OEM pads again, they aren’t great.

Dont know about the Ferrodo ones but Ebc have an option for the brembo caliper

They were very helpful with me to clarify exactly the ones I needed byt email (TRW caliper)

I have just thrown some reds on and they are brilliant compared to the OEM crap, I went with a standard brembo vented disc as well

reds are "enthusiastic" road driving but not trackday, however they do allsorts of types for what you need

Linky to EBC

 

[Slickric21]

I’ve actually just ordered the EBC Reds in the end, fronts for the 370mm with Brembo Caliper and rear 310mm ones.
Looked good and were half the price of Ferrodos.

I also ordered new Discs,

Zimmermans with drilled holes for front 370mm

https://m.autodoc.co.uk/zimmermann/8761331

Brembo xtra (drilled also) 310mm for rear

https://m.autodoc.co.uk/brembo/8713873

There is a Zimmerman rear 310mm drilled disc option link below, but I got the Brembos very cheap on a flash sale (£77 for a pair) so chose them.

https://m.autodoc.co.uk/zimmermann/1738330

They both were significantly cheaper than OEM.
I have noticed some Issues with my current discs after 15k miles, I think due to rubbish pads being fitted OEM, so I’m changing the lot for good measure.

For reference the Ferrodo part numbers I wanted for 370mm and Brembo caliper were….
DS2500 = FRP3067H
DS Performance = FDSR3067

The OEM number is 8J0698151M

For reference those Ferodo parts you quote are NOT correct for the Cupra - or other VAG models.
They are missing the wear indicator notch.

What was the EBC part you brought?

For reference; 8J0698151M is the front pad OEM number for the 370mm disc Brembo caliper brake.

Would be interesting to see photos of the EBC pads you brought?
And photos of the pads & discs vs the new discs?

I'm lead to believe the Ferrodo ones are correct for the 370mm disc and Brembo Caliper on the R ST or Sub8 pack.

The EBC ones are the same I assume.

Yes, they'll fit the caliper - its just a common brembo pad shape - but with no WI notch, so not ideal for a road car!
I would just cable tie the WI out the way behind the wheel arch liner.
The EBC ones according to their ident drawing have a WI notch. We'll see?

Those rear EBC pads have an R90 number on them - but can't see any images of the back of DP32070C, so it will be interesting to see if they also have an Reg 90 number? (probably E11 90R ..... ) If not they are actually illegal for road use. Whether anyone will check/insurance? Probably a very low chance.

Do you do any track days of is it just a road car?
What didn't you like about the OEM brakes?

 

[Slickric21]

I’ll send pics when I get it all.

No track days, hence getting Reds and not Yellows (and therefor not the Ferrado ones also as overkill)

OEM braking system on R ST is ok, but myself and couple others owners have noticed the pads are damaging the discs as they wear down, there is some sort of metal pin system inside the pads ( 8 of them) scoring the disks badly.

I’m changing my rears also as ive got horrible scoring on one of those also, and the Brembo drilled discs were cheap as anything (£77 for a pair) do I thought sod it,do the lot. Plus they are drilled so look better.

EBC pads I’m hoping will be slightly better braking (but not fussed if not), will not damage discs as they wear, and give less dust !!!

Think you should feel a difference from stock.

I finally had the chance this morning to unleash them through some twisty stuff in snowdonia and am very happy.

Consistent pedal, no pulling and I didn't notice any fade even when working them pretty hard.

 

[CupraRST]

Interesting thread. So far the only problems I have with the OEM brakes on my R ST are extreme braking dust at the fronts. P
Plus directional front discs that only come in one direction, so one of them runs in the wrong direction.
The aluminium centres of the front discs are impossible to keep clean, or is there a way?
Do you mount your new discs to the OEM centres? Or are they in one piece?

 

[Slickric21]

Yeah the dust is extreme, one of the reasons for going EBC Red.

That centre section is impossible to keep shiney as it’s not got a coating.
You could clean, sand and paint it down and it wouldn’t look dull or rusty, but I’m just swapping the disc due to the scoring.

It’s a one piece swap the whole disc, they aren’t like some of the aftermarket ones where the disc is detachable centre.

I’ll update with pictures as and when parts start to arrive.
My front discs were ordered from Autodoc so they could take a while.

I'll be looking forward to your experiences with the EBC Red pads. Also with the new discs (front and rear).

If the new fronts are one piece, how much heavier than the OEM discs will they be? In theory that will be a negative change in driving experience, but will you notice?

They told me that any coating on the centre part will burn away.

Did the front pads distroy the discs without any warning?

They are 1Kg lighter per disc than the OEM ones.
OEM are 13.2kg per disc, Zimmerman are 12.1kg
More expensive disks such as these below are 11kg per disc, as are most of the perfomance orientated ones.

DBA’s 5000 Series T3 is the ultimate in direct replacement 2 piece performance brake for high performance street & track applications.

progressiveparts.com

Lets be clear here, there is nothing special about the OEM braking setup at all, poor disks and crap pads.

Ive painted non contact areas of discs with special silver paint many times before and it doesn't burn away. It only burns away if it comes into contact with the pads, which on our discs it wont.

No the pads wear down gradually as normal, and then as they get low the metal rods start to protrude these damage the disc.
There has been specualtion its a purposeful design to make people buy new discs !!!!

To be clear, the Zimmerman discs are not 1kg lighter than the OEM discs.
I have seen the OEM discs listed at 11.29kg and killer brakes have them at 24kg for 2x which may include the box?
So the OEM discs made by SHW in Germany are actually a little lighter than the 12.1kg Zimmerman's
This makes sense as Zimmerman have changed the tophat design and include more alloy than the SHW.

Incidentally SHW invented/patented this pinned composite disc design with an alloy hub, first used on the old M3's, and subsequently used on the majority of serious high performance cars with an M/RS/AMG badge. The original R32 had SHW pinned discs - but the later versions and even the R Golf has full cast iron (cheaper and heavier!).
These OEM discs are a lovely piece of machining - but they are expensive!

I do agree that generally German OEM pads can/do tend to produce a lot of black dust. That is a trade off they have gone with for the European market.
Friction/Tribology - is massively complicated and it is impossible to have a friction material that does everything the best - just like tyres, there is ALWAYS a trade off. You will notice 'performance' oriented friction never show their cold performance friction coefficient - its always from 20 - 50 or above 100. That's because they have made that trade off to prioritise high temperature performance and stability at the expense of cold temps performance - fine for a track car, but something to keep in mind on your first stop in the winter. With modern over assisted brakes it's probably not a big/noticeable issue - but it would make the ABS/EBD & TCS have to think harder. With my V8 kitcar and my un-servoed brakes - I find my redstuff pads rubbish until they have some heat in them.

The trend over the last 10-15 years is to use a higher carbon alloyed iron for the friction surface - which is actually softer than standard base gray cast iron - but has some beneficial properties such as being better damped (for noise) and better at thermal fatigue. The downside is it being softer you probably have to change the discs with the pads - rather than getting 2 - 3 pads to 1x disc.

The pins in the friction are there to help stop the edges lifting under higher temps/loads. I would think they are made from some soft metal (brass/copper). Discs can develop grooves for many reasons, often corrosion and lack of use can accelerate this. Corrosion eats deeper into the iron and doesn't fully get cleaned off. Do your grooves in the discs exactly match up with these pins?

 

[Slickric21]

Ive seen the OEM discs listed as 13.2kg and 14.48kg, and 27.18lbs (which is 12.33kg)
I went for the middle one !!

Either way I’m not too fussed about marginal weight saving, if I wanted that I’d have bought the DBA ones in my post above.
Someone on the Cupra Facebook forum who has the DBA discs said there was a noticeable weight difference between DBA and OEM, and DBA’s are 11.2kg, as well as very nice upgrade in stopping power (used DS2500 on both discs)

Edit:
Yes the grooves match up with the pins on the pads

Agreed on the weight saving not being important or even noticeable.

Not a fan of the DBA rigidly bolted mounting the bell to the friction ring TBH. Prefer the SHW pinned design or fully floating.
As the disc friction surface gets hot it expands radially. Usually 'racing' discs which a floating have slots and bobbins to alloy the discs to expand and contract uniformly without distorting and coning.
The SHW OEM disc pins are centrally located which minimises coning, where as the DBA bolted design is offset to one friction plate - which has the same limitations as standard full cast iron discs.

How much material did/do you have left on the pads? Would like to see photos of the worn pads and discs?

 

[Slickric21]

My pads are about half worn now, Ive not had them off yet, but my disk is looking like the one in this picture from another R ST user.


Note the last one is Zimmerman vs OEM disc for comparison of design

Interesting, thanks for sharing.
These are off another R ST?
The wear indictor has been worn so judging by this they are probably due for a change.

 

[Slickric21]

Yes they are off another R ST, I’ll post pics of mine when I do the change in a few weeks.

My disk looks the same as that one in the picture thou so I’d assume my pads are the same.

 

[Slickric21]

Just a little update on this.

I did the disc and pad change a few weeks ago and very happy with the results.

My disc and pads were starting to look just like the ones in the pictures posted above (scoring on disc from the pads)

I was so focused on doing the job I forgot to take pics as I went along, so pics below are taken the other day after a few hundred miles of the new discs and pads.

Very happy with the EBC red pads, minimal dust and after bedding in properly there is a noticeable improvement in stopping power over oem.

The Zimmerman front discs at half the price of OEM seem like a good buy, good quality and have the anti rust coating that the OEM discs lack.
I did weigh them before putting on and came in at 12.1kg.
The OEMs coming off were 11.9kg so there were a tad lighter after all that, but they do have ~5m lip front and back where they have been worn down, so it’s conceivable they were heavier when new ??
The rear Brembo discs were a little lighter than the oems coming off (sorry can’t remember the figures) so that offset and extra weight if any of the Zimmerman fronts on the cars overall weight. Negligible amounts here anyway tbh.
Quality of these rear Brembos is very very good and for £77 a pair are great value imo.

Disc part numbers are listed in posts 3, and EBC Pads in post 5 for reference for anyone.
Car is 2019 R ST with 4pot brembos on the front.

 

[Andyoxon]

So reading this thread I’m still not sure if the Zimmerman disks are better than the OEM ones or just cheaper, need to replace my disks sometime soon are there any other options looking for the least likely to warp don‘t need to be the cheapest. I don’t track my car but do spend several weeks at a time on the Isle of Man early morning drives allow hard use of car especially coming over the Sloc.
