I've noticed that once I have gone up on the power tha Yellow Pads all round are not cutting the mustard.
I'm having to dab the pedal a little bit before applying pressure.

I'm running 450bhp on the OE Brembo calipers with Brembo Sport uprated discs (drilled) and EBC Yellows all round.

Was thinking of trying a set of DS2500 on the front first but not sure how the bite will be on the discs?

Has anyone else got these discs with pretty much the same power? What is your set up.

Cheers

Don't think the DS2500's will be any better mate, I'm running Pagid RS29's on Brembo 4-pots and EBC discs and I'm thinking of an upgrade to 6-pot AP's for better stopping power.

If you look back over the years 330mm 4-pots on the front were 'massive' on a tuned cossy with 350bhp, but these cars were lighter than ours and you've got 100bhp more.

Probably worth biting the bullet and sticking 355mm 6-pots on the front.

I respectfully disagree, Anders.
The Brembo's are more then enough, if fitted with decent pads.
Try Performance Friction 01 Compound or Carbone Lorraine RC6, and you will be amazed with the difference.
Those pads are a world apart from either the Yellows or the (better then the Yellows)Ds2500

If you cant strech to the expense of AP racing 6 pots then take a look at the K sport 8 pot 330mm or 356mm set up.

I had the 4 pot brembos with PF discs and PF pads fitted to my 346bhp wr1 and still found the brembos poor so upgraded to the K sport 356mm set up with the ds2500 pads fitted. Had this set up for about a month now and the diffrecnce is night and day between the brembos!

The Dynamixs Time Attack team run the K sport set all round

Give Bren a pm and see what price he can do them for if you are intrested, the link below is for the GB that was running but think the GB is finished now.

I belive that Ian at Godspeed dose his own kit for AP racing set up and at a very resonable price.

Good luck with what ever you decide on!

Fit a set of Performance Friction Pads and you'll be suprised just how good the Brembo setup can be: http://www.superhids.co.uk/performan...-compound.html

Thats what I meant when I typed the 01,s.
The 11 Compound is much better, but I always mix them up.

Cheers guys.

Was looking at keeping he Brembo's to be honest. May give this PF ones a go.

What these like from cold? I remember a set of DS2500 I had that you needed to give them a little bit of heat for them to work etc.

I have been running the OE Brembos with PF discs and Z compound pads for about 2 years now and they are fantastic.

Done various days at knockhill as well and never had any fade.

They are great pads when cold and fantastic when up to temp.

Even had compliments from guys with AP on how good they are.

This is on an 05 STI with 400bhp (also got braided lines fitted)

Before I hade the DS2500 pads and they were OK but not as near good as the PF's and a lot more brake dust as well.

Bob,

Thinking of given the PF ones a wirl after speaking to a few users with them over the alst week or two.

Just wondering if you feel the pads would be ok on my Brembo sport discs (Drilled) on a harder pad etc?

With a harder pad you will generate a lot more heat , so you can end up cracking a drilled disc around the holes , I would fit the pads and just keep an eye on the discs every month , when they go fit grooved only discs.
I can also supply you performance friction discs and pads

Hi Steve,

With a harder pad I would expect some surface cracking on the disc. Plain or grooved discs will do this also, just that will your Drilled Brembo discs it will appear around the holes.

Usually nothing to worry about if you keep an eye on them. Ideally with that type of pad something like the PF discs or BrakeTech discs would be more suited.

Give me a call if you need

Thanks Ian and Bob for the feed back.

I was worried about the cracks on drilled set up. I keep an eye on it even now with people say they crack easy.

I'm sure Ian being in the Brake business you will agree that drilled discs have come a long way from even say 5 years ago?
Do you know if the Brembo sports are made of a harder/better cast that the standard OE discs? OR are they just for looks?

Bit stuck on what to do now? Wasn't banking on changing the discs for a while but if the PF are that much harder maybe something to think about? Bugger.

Will be in touch guys.

Hi Steve
Drilled discs haven't come on really , its the pad materials that have seen vast improvements over the years , the problem with a drilled disc is that you are drilling through the grain structure which weakens them , some top end cars you see with drilled discs as standard have the discs cast with holes in them and then machined finished later , so the grain structure flows with the shape of the hole , but even these will end up cracking with hard track use.

You don't need to go to the expense of a 2 piece disc and bell set up to make them reliable , a good grooved discs would work well for fast road / track use , a 2 piece disc is just a better version , these are lighter so you get less unsprung weight , less heat transfer through to the bearings as aluminium dissipates heat quicker than a cast iron/steel disc , and if you do get them really hot , they don't go out of shape when expanding like a one piece disc would so less chance of them warping

Hope this helps
Cheers Ian

the Brembo "sport" discs are far better quality material & castings generally than some of the lower priced drilled discs you see around and hence will fare far better in terms of life/performance and the all important cracking issue........

Alyn,

That kind of add's fuel to the fire from my point of view? Looking at the recent EBC thread would anyone know how different the compound is on the NEW yellow stuff pads are.

Have they come along a long way and on par with the PF,DS2500 range now?

Steve

tony de wonderful

So you changed pads and went for bigger calipers/disk, you got better peformance, and you only credit the bigger calipers/disks? Did it not cross your mind that maybe your original pads were pants?

356mm disks weight a ton BTW.
