Come on Mike, when are you going to get some REALLY big ones ? :laugh:

Collected them tonight :-)

SWEET, they look the part mate. When you going to get them on there ? Whilst I have you, did you notice a difference when you fitted the R32 rears ? I picked up a set and will be fitting them shortly, but wondered if they made a real world difference or only showed their potential when REALLY pushed hard ?

Fitting Saturday morning.
I'll be honest I haven't driven / braked the car hard enough to make the most of the s3 rears but I'm sure they'll help keep things in check they certainly get positive reviews.

Are they simply a harder compound and not as responsive until warm?

Its usually because they are too bitey.
There is a legal limit on how snatchy pads can be believe it or not, its some EU bull as usual.

It's no bull.
ECE R90 Reg rules the compatibilty of brake pads for stock brake systems.
Like Beddie said tolerance is +/- 15 % of COLD friction.
If you fit different makes of pads front and rear and on one axle you have
+ 15 % and on rear - 15 % this seems very much tolerance. Even more
would be TOO much !!
--- Quote from: Beddie on January 31, 2012, 10:34:53 pm ---Any brake pads within the EU have to conform to 'Regulation 90' (ECE R90), this stipulates that any brake pad for road use has to comply with the requirements of reg 90 in respect to performance, fade etc to within a tolerance of no more than 15% of that of the original part...
The 15% tolerance is both under and above the original reference limit so means that any pad that exceeds the performance of the OE part by more than 15% is not technically road legal, coupled with that is also the fact that most 'limited' market pads (fast road/track pads etc) are never sent off for reg90 approval by the manufacturers due to the prohibitive costs involved for such a small relative market...
In reality a pad compound such as the Ferodo DS2500 will exceed the performance of the standard pads in both cold and hot benchmarks :happy2:

Yes, many pads exceed R90 Reg but too much friction may be too much
for brake balance in stock systems if combined with lesser pads.
I guess some companies don't like to pay any money for approvals as well.
Back to topic:
I'd go for a NQSBBK instead of the S3/R setup, but don't matter which
OEM brake you choose or stay with there are some very good aftermarket
discs and pads for fast road and light track use:
- Tarox Zero, Sport-Japan, G88, F2000
- EBC BlackDash, TurboGroove, CarbonBlade
- Ate PowerDisc
- J-hooked Brembos by DaveB
- CTF/Sandtler GT
- Ferodo DS Performance, DS 2500
- EBC Red + YellowStuff
- Ate PowerPad
- Performance Friction PFC01, 06, 97
- Pagid RS4-2, RS4-4
- Endless MX-72
I personally prefer F2000 discs and will go for RS4-2 or MX-72 pads next.
You should consider solid brake kit bushings as well. Very worthwile mod.
mkviken:
i looked into them bushing kits but they're about £100 or so.
i think i would just go for it and put that money towards the BBK instead.
Mk5 GTian:
My discs are curling over at the edges. does this mean they are on their way out?
How much is the NQSBBK please, and how much would should I pay for the OEM discs with those Ferodo pads?
Cheers,
Ian
