As my brakes are screeching i might change the pads for some yellow stuff ones .

What the parts number for the fronts and the best place to buy them ?

Finally drove the car. The pads feel great. Didn’ t take more than a few miles to start feeling bedded in and plenty progressive feel from the pedal...! Pretty happy with them tbh......

I'm fitting DS2500s tomorrow... have used before and always impressed... not been able to do a side by side with EBC but most Ferrodo guys would swear they're better. About 145 a pair though front and back so not a cheap option... but the brakes are disappointing in OEM spec for me so I think it's work the investment...

Got Ferodo on mine and the difference is chalk and cheese. A noticeable improvement.

The Yellows I've put on my GT have turned braking from "I brake gently from a distance" to "I wonder how late I can brake".

Massive improvement.

Hear Hear, I second that, by the way for those of you about to buy from ebc brakes direct, enter the code IAM 485967 in the code box at checkout, should equate to about 10% discount.

I have ordered some DS2500 for mine today - Yellow stuff are mustard for stopping power but there is a lot of dust and they chuck out bits that weld themselves to the wheel finish. The reports I have is that there is less dust with 2500s and I am looking forward to finding out.

I've just taken mine on a bedding in run with the DS2500 pads... impressive! I wasn't quite at full emergency stop levels... but the bite was sufficient to pull the fairly snug rear central armrest down! I don't even think I realised that was there before :)

I will do a more subjective real world driving test this weekend but after initial install they seem the business. They were certainly good on a GTV Cup I had years back.

One note... I believe a common problem with Brembo calipers... mine did have a little 'plate lift'... so a slight amount of surface corrosion underneath the guide plates on the front. It was only really effecting the inboard side of both fronts... but it made the pads very tight. You could see they had started sticking a bit because the inner pads were 20% more warn than the outers which still moved easily. I did try and remove the plate bolts but OMG they are difficult. Having read more about the drama people have gone to getting them out... and given mine weren't that bad... I went with the file option and just took a hair off the pad plates to ensure they moved freely. I will keep an eye on them but I am sure they will be fine. If the calipers were knackered I would taken them off and re-build properly... but to do all that for the sake of the 0.5mm I needed when overall they're in great condition... not now thanks.

Anyway I mention this because I imagine most who are doing this on 12+ year old coupes will have the same issue to some extent... you'll be in the lucky minority if not from what I can tell... so be prepared to check this and make sure they are a nice fit with suitable clearance. Don't just reach for the hammer to jam them in... good way to ensure squeeling overheating and uneven wear. I would hope a specialist would always do the right thing here but anyone less than that is probably just going to jam them in there... so my advice would be to take an interest in it personally... whether you're fitting yourself or not.

Hope that helps, either way... Ferodo or EBC... both a massive improvement on stock I am sure. Just make sure they are bedded in properly... the process is er.... a little different than a normal road pad. Enjoy!

Cheers,

Chris

Where did you order from - I couldn't see a drop down for 4200/GS on the Ferodo web site...just 3200.

I ordered from Amber Performance who have been listed on here previously. They were very helpful. He did a full set all round for £300 delivered.

The Brembo calipers on 4200 are pretty standard things so pad availability is pretty good.

The Ferodo racing website is a bit sneaky, it doesn’t list our cars. If you put FCP1298 into the search function suddenly they appear. Those are the fronts, rears are FCP451. All suffixed with H for 2500s.

I was advised to use 2500s from a reputable source and I did. I have since used yellow stuff. There’s, perhaps, a few on here that will confirm I use mine to the ragged limit, and I’m still using yellow stuff. Make of that as you will.

This is a fair point. I haven't got on with them, I find they vibrate a fair amount - I will know for sure when we get back from LM!

Tbh, like the original Brembo pads, I find them a bit wooden and lacking cold ‘bite’.

I found the EBC yellow stuff pads okay but not great, no feedback and on a track day overheated in a short time frame. Ferodo DS2500 much better compound for track, will come back after a quick cool down but the EBCs need much longer to cool down. Road use DS2500 seems to work at lower temperatures, albeit still need to get some heat in pads. Attached pictures of part numbers for F&R Ferodo DS2500, I paid £130 all in. Bargain.[/ATTACH]

I was very happy with my EBC Yellow on the fast road driving and it seemed good at my first track day at the very demanding Istanbul Park F1 Circuit. But after 2 x 20 mins, my pads cracked which had probably only in total 5k kms. As I blamed the discs which probably also caused no good bedding, I'm now again with EBC Yellow and did 2 track days, one being rainy so slower and cooler rounds and second with tyres almost gone (as Trofeo R did not make it on time) for 20 mins but was enough to kill my front tyre.

I did a search on youtube and found this which seems Yellow was not the right choice for him for heavy track and his car weight/power ratio:

Reading above youtube video explanation, I checked below link:
https://ebcbrakes.com/ebc-brake-pad-selector-tool/#pad-result

After entering weight/HP for Gransport, selecting Track Driving & Race, option is Blue (which they still say it's good for road) and Orange for even more demanding situations. You need to read below if you want to go with Blue at least because it could cause issue with your insurance:
https://ebcbrakesdirect.com/ece-r90

Below is the summary from EBC:
"For those driving higher performance vehicles <hard> on the road and occasionally on the track, a set of EBC YellowStuff is the best option and these pads also DO have R 90 approval and are therefore perfectly road legal. That leaves EBC’s ultra-performance Blue and OrangeStuff grades for drivers who push their vehicles to the limit on road or on track. These materials don’t have R 90 approval (apart from a small range of BlueStuff pads which do) but the levels of performance offered by these materials is undeniable."

As my track needs very good brakes to slow from 210 to 65 kmh, I will reconsider yellows after seeing if they cracked or flaking:

EBC has also new stuff coming soon. Maybe 4 pistons is not an improvement but they claim differently saying large is not better. Interesting note for yellows noting "for moderate track use". Not sure of course if they come for the size of 4200. As far as I know, FD is also working on upgraded lighter front brake kit.

Regarding experiences mentioned above:
BennyD: was your experience also for track use to compare DS2500 vs Yellows?

Panicracing: what was the bedding procedure for you for Yellows? I assume you didn't take them right to track. They need 300 kms or so city driving stop & go before and then some bedding hard slow downs. Also were they bedded to new discs or used ones?

I hear very good things on Pagids, the version they use track oriented Porsches. More expensive for sure but anyone with experience on Pagids vs Yellows? How about experiences with Carbon pads like from FD?

One last thing which I knew wrongly. Even though DOT 5.1 should have higher boiling point then DOT 4, this also depends on the ingredients also in the fluid and some DOT4 are better then other DOT 5.1:
This note from EBC again: .....kits are supplied with 1 litre of BF307+ super DOT 4 brake fluid. This fluid has a 307 degrees C boiling point, a significantly higher boiling point than standard DOT 5.1

Standart DOT 5.1 has 270 degrees C:
