Rear Brake Pad Upgrades....
gazbutS3:
I was under the impression the S3 and R32 rear set-ups are the same, might be wrong though :laugh:

My understanding is that the DS2500 pad performs better than the oem pad regarding whatever heat generation there is or isn't.
So, stokey, tell us more about your S3 rear brakes - Disc size, pads used, weight, any pics?

Pads used are the std S3 rears, allied with 310 x 22 (i think) mm Discs. The pics are in the thread linked below. The weights are heavier, due to larger dia and thickness disc used, also the caliper is larger. heavier by how much, I dont know.

@ DaveB,
Yes I definitely will be asking AP to clarify about the 85%. But whatever the braking distribution is, my car doesn't front end dive or handle badly as a result.
Whereas I can understand how a certain amount of heat generation is a good thing, I think we all know that too much heat is not a good thing!
It's well known that DS2500 pads, like tyres, need a bit of heat in them to work better but that's easily generated.

Dont know whether its an installation issue but the 2500 compund has been getting a bit of a slating recently over on uk-mkivs, the pad of choice over there at the moment seems to be the pagid blues

....I don't read the uk-mkivs forum but I'm not inclined to view such information as reliable. Someone posts a negative opinion which then starts others wondering and naturally it spreads. Whether the negative comment was right or wrong it happens everywhere on the internet (and elsewhere such as public confidence in the economy etc). What's more important is who expressed the opinion originally and on what basis. Another aspect of car forums is how so many are primarily led by cost considerations in their judgement of products - Perhaps Pagid Blues are cheaper (I don't know).
Do you have a link to this slating of the DS2500's please? [mine have just arrived in the post!]
Thanks :happy2:

@ Quality Dave, aka stokeballoon - Thanks for that info and very helpful link about your S3 brakes.

Just thinking aloud, but both the oem R32 and S3 rear brakes will surely have been designed to work on 'driven' rear wheels (be it Haldex or quattro).
Does this suggest that fitting them on the rear of the FWD Mk5 GTI may be overkill?
Please note that I'm only raising the question and not saying that this is the case.

Since i fitted my S3 rears the car is a joy to drive, the car feels balanced under braking, and the rear never gets "tail happy" under braking.
i was asked by an independent engineer as to what brakes I have fitted, he was impressed by the overall feel of the car, and he has the pick of any braking system, being in the 'race preparation' enviroiment.
I therefore rate the S3 rears was the 2nd best mod behind fitting my RNS510.
This is my opinion, and I would do the same again.

....But didn't you also fit S3 front brakes? So how are you able to judge the benefit of fitting only rear S3 brakes to a GTI/Ed30 as a mod?
