Hi, anyone has tried ferodo ds3.12 on the front with stock brake system? Abs totally disabled

Cheers

[piwo]

I use ds uno on the front and ds 1.11 on the back. very good pads. they catch from the cold. Much better then ds2500. ds 3.12 is available for both front and rear. the disadvantage of the pads that they stick to the disc when standing for a long time and then when moving it crumbles. but they stops incredible.it heats up the brake fluid very much

[Simons]

Thanks Piwo, I was thinking on fitting ds3.12 on the front and CL RC6 on the rear. I didn't find ds3.12 for the back...

What pads had you got before?

And what about the sound, are they noisy?

My car came with ds2500 on both axels

ds pads are not very noisy. nothing with carbone lorraine is noisy. the ferodo will sometimes make a slight squeak when you brake lightly. but not always.
 
I have ds2500 before ds1.11 And dsuno. Ds2500 is sh*t. they did not slow down in cold, and also poorly in heat. ds1.11 and dsuno are smashingly better.

[Simons]

Thanks!!

And what about the bite? improved or hasn't a lot of bite

[piwo]

the bite is definitely better.

Sorry but DS2500 stop from cold.

[piwo]

No IT doesn't stop from cold. Ds2500 is sh*t.
has a tremendous delay in braking response when cold

You can sort of understand pad behavior by looking at the friction rate table.
https://www.ferodora...ake-pads/ds2500

 

If it needs to go up in temp a little, it means they do not work optimal at cold bite.

If the line is flat from beginning, that translates in good cold bite.
The higher the friction rate, the more aggressive the pad. (When running in the optimal temp window)

[Simons]

I think that Piwo wanted to say that there aren't too much difference between cold and hot. This is what I see on my car.

I found this graphic about Carbone Lorraine, is this real? Because all his pads are mainly flat...



Ferodo

[piwo]

I wanted to write that the antediluvian ds2500 does not inhibit cold, unlike the new ds1.11 series which inhibits cold.

it makes sense to compare the coefficient of friction for a given manufacturer and not between them, because each one measures as he pleases.
0,6u Carbone Lorraine that is not 0,6u ferrodo.

Ok! Let's see if someone has another experience with this ferodo pads

LC RC6 are good pads, but noisy and hasn't got too much care with the rotors

[smiley]

The specs of these 3.12 look good.

Just buy them and let us know what they do

I have them on the front and they work from cold.
They are similar to mintex 1144.
They are certainly not a good track pad but they work from cold and are better than a street pad while retaining low disc wear.
They don't have a high friction coefficient but still better than a street pad.

[piwo]

I had ds 2500 on front and ds 1.11 in rear And
it was very interesting comparation. Always bloked rear. On cold And on hot on trackday And this config was fine. I don't like when front blocks And i like when block rear. Now i Has ds 1.11 rear And dsuno front and it's worse solution. Ds1.11 front DS3.11 rear could be better.

Your front camber setting > minus 3° may not help either...

[piwo]

This camber is for this year.when i had ds2500 IT was -2° in front and -3° on rear.

for now no problem with this.

friction is not surface dependent but strongly temperature dependent. it is better to brake a smaller tire surface, but not overheated at the edges from too small an angle

😁😁😁 For the front axle surely I'll buy them. But the doub it's on the rear, ds1.11 or RC6

I usually drive on open roads and traffic, block the rear isn't funny anyway...

I only found ds1.11 as top of the range for the rear brakes.

What you tell is very interesting, because on the rear you have worst calipers, traction force, more weight, I think less brake fluid pressure ... and you can block, so the pads has a good braking power or bite, I don't know if you block for the first instance or later. A good test, for me, will be fit rc6 on the back to see if happens the same and have more or less braking power/bite.

What tyres have you got?
