Hi Gents
My Edition 30's brakes are definitely coming to the end of their life and wondering what to do - upgrade to an S3/R32 larger disc combo or perhaps (for now) an uprated front disc and performance pads kit? Does anyone know the best alternative to OEM discs? I understand the S3/R32 discs and calipers are quite a lot heavier than standard so perhaps negates the added efficiency of the bigger discs.....My car is standard in all respects at the moment but I'm considering a REVO remap in the future.
Can someone tell me if the weight difference is noticeable when driving?
Many thanks

The benefits of the S3 brakes VASTLY out weighs the drawbacks of there weight. They add IMO added feel to the steering aswell as much improved braking. That said i chopped mine in for Forge 8 pots with 356mm 2 piece discs so what do i know :laugh:
-
Paul... they are loads heavily and it probably makes the front end a fraction crashy, but worth it for the stopping power.
I would suggest buying some OEM 312mm brake discs and some Ferodo DS2500 brake pads.

Cheers Rich + RS6BRIT
You said the same when I saw you Rich - my memory is fading fast!
I'll order them up from TPS which is near me in Croydon....do you have the disc part numbers by chance?

You could buy the NQSBBK from DaveB

Drove mine last night for 1st time in a while and was reminded how brilliant te NQSBBK.
I'm a loon for changing to brake setup number 5 Next week! :laugh:
Oem Cupra front / oem Cupra rear
OEM Cupra front with drilled discs / OEM Cupra rear
Db9 front 345mm Cupra rotor / oem Cupra rear

Next week...
Porsche 996T calipers, 350mm jhooks, OEM Porsche pads front / S3 rears j hooked
Suppose technically it's seven setups :surprised:

Jeez Louise!
And you don't drive it much Mike?!? Hope you've managed to sell on the bits!
I think I'm going to see how a new set of OEM discs go unless anyone has a better idea. Slightly concerned that Ferodo pads according to their website aren't for road use. Are they simply a harder compound and not as responsive until warm?

You should feel an improvement with the feredo pads. Especially if your current setup is hammered.
Could try drilled or jhooked oem discs too.
Beyond that DaveB is your man for upgrades :happy2:

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. EBC bluestuff pads had trouble getting EU approval on this ground but i believe they are now approved for road use.
I think it has to do with passenger comfort as if a pad has to much bite it can be uncomfortable for the passengers at low speeds.

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

This will be me now. :innocent:
My ideal setup would be lightweight 4 pots and 2 piece 345mm rotors

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:

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.

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 !!

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.
-
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.

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

They are getting a lip on them... which is perfectly fine unless its more than about 2mm each side.

Thanks Rich, probably not far off that TBH. any idea how much roughly for the OEM 312 discs with Ferodo pads? Can I keep my calipers with these pads?
-
Ferodo 2500 pads
Front FCP1765H £164.71
Rear FCP1636H £126.73
Prices from Dubmeister in Bridgwater, Somerset.
Isn't that a lot of money for pads alone? £290?
