Not EC90 approved as OEM replacement parts, same as 3000/1144/1155/RC5/6/8, etc, etc.

Neither are grooved/drilled discs unless they are OEM pattern, and neither are my wavy discs.

Does that technically mean that anyone with these parts doesn't have insurance? Also where do you stand if you declare non road legal parts to the insurer? Are you insured then? Or will they find a way of backing out if they wanted to.

technically yes you'd be uninsured, but along the same vein as if you use a 50 profile instead of a 55, not right for the car but they work, ish.

At least 50 profiles are E marked though (or whatever the relevant accreditation may be). I don't know why I am asking this I will be fitting wilwoods and spacers and have 1144s on the back.

Still insured so long as you tell your insurance you've changed from the original braking system Dunno

EC90 is a regulation for replacement fitment pads which means they have to be within a performance and dimension tolerance of the originals, made in an accredited factory and sealed in tamper-proof packaging.
Which means any parts that exceed the performance of the standard parts can't be accredited Doh

It's to stop some dodgy dealer selling a little old lady DS3000's to be fitted to the back of her corsa and her ending up backwards through a hedge...

I thought the higher ones were ceramic?

Could you at least try to post in the right section, and try using the search before starting new threads. All the information you want already exists and it'll elicit a much more positive response from the rest of the members on here if you put a little more effort into researching yourself before asking daft questions.

Well, the top end ones are yes, ceramic doesn't have the same trouble anyway because they don't move the same way with heat, and they need the holes to get more leading edges to bite into for when the brakes are cold (same principle as the wavy ones really)

I have run DS2500s on a few cars now and they are great. Pretty sure my insurance knows about them, but will check anyway.

I fitted mine at the start of 2006 along with the BD Combi disks. The disks need replacing very soon now, but the pads have plenty of life left.

+1 I have the standard GTi6 brake calipers and discs on my 205 and have DS2500s installed as well. Awesome stopping ability and did very well going around the Nurburgring for 4 days at the Easter Weekend. Big grin

so by the sounds of it the best setup is Original Brembo vented disks from GSF and DS2500? Tried and tested?

Where are people getting the pads from and whats the average price?

I've heard some horror stories about drilled rotors. Namely that the edges where they've been drilled are prone to cracking when they get hot.

When you drill a hole in metal the hole becomes a stress concentration. The act of drilling the hole can also cause micro cracking, which in time can propagate from the hole across the disc, as shown in the earlier photo. The expensive ones are cast which avoids the introduction of micro cracks from the drilling process, but these cost a lot more to produce.

In terms of brake set ups, I've had standard discs and pads for pug, standard discs with green stuff pads and vented brembo discs with Mintex M1144 pads. I've also borrowed a 6 with the exact set up you are looking at.

I thought standard pug set up was pretty good, the greenstuff pads had less initial bite but didn't fade as easily and the brembo/mintex combo I'm running now is by far the best of all I've tried.

I didn't get on at all well with the drill/groved discs and greenstuff pads. First time I came to a roundabout I braked as I nornally would and thought I was going to go staight across it Shock

aww already recieved em! Sad

lol i wanted ferodo ds2500s but the guy wouldnt sell em me for road use ????

Weird. I have DS2500s from Demon Tweeks and they are brilliant brake pads.

As for Greenstuffs - you'd be better off sticking your feet out of the door and pressing them on the floor to try to slow the car down. LOL

Seriosuly, watch out for brake fade with greenstuff - you will get it a LOT.

So that pic shows a front and rear disc for the same side by the looks of it? From the direction of the the grooves I'm pretty sure that the two discs pictured are both for the drivers side.

Does that match with what you thought?

Are they Black Diamonds or something or is it just the light that makes them look black?

They are excellent with DS2500's and some Castrol Response Super Dot4 Brake fluid. File the leading and rear edge 45 degrees to help bed the pads in and prevent squeal and add some copper slip on the rear as per Welly's FAQ.
