They decent for delivery?
Never used them.
I've just ordered front discs from them there so I'll find out in due course.
Any update on this? I need discs all round for mine again.

Think I paid £240-250 for the pair on mister auto when they were doing 40% off and the rrp was a lot lower back then anyway.

They should last for ages with no track use!

Mine were last changed in 2010 going by the paperwork. There is an obvious lip on them now though and they're not the cleanest. I didn't realise the quoted minimum thickness isn't that much different from the new thickness, only 1.6mm of overall wear permissible. (32mm new/30.4mm min.)

I wouldn't worry too much about the wear limit, as long as it still brakes true and the discs are clean, I would run a sanding disc round the edge of the disc to take of the edge and just keep an eye on them.

Delivered today. Always forget how heavy brake discs are but these are massive.

If they are OEM ones they will also be L / R specific, make sure you put them on the right way around, the old ones on my car were the wrong way around which I started to copy before realizing!

Thanks for this info, are the Ate disks from the German supplier the same as the ones supplied by BMW? If so, this is a huge saving on the dealer prices! How much was the delivery charge if you dont mind me asking?

What pads did you fit to compliment these standard discs? Do you have a link?

I've tried for ages to establish the OE brake rotor supplier to BMW for the E39 M5 to little or no avail. Chances are that it is ATE but there are a couple of other possible manufacturers so cannot be 100% sure. ATE produce high quality braking parts so I wouldn't sweat the choice issue too much since the price from the German supplier is very good.

However..

...Check that the German outlet actually has the rotors in stock before you press the 'Buy' button. I tried to buy some from this source last week and got my payment bounced back to me minus currency and bank charges BOTH ways ie. £ to Euros, then Euros to £. RBS, my bank, certainly pulled my pants down on that particular transaction leaving my £20 in the hole with nothing to show. Not much money in the overall scheme of things just bloody annoying.

Brake pads. Textar are OE pads for the rear brakes (the ones that came off mine had been fitted by a BMW dealer and had Textar markings as well as BMW logo/part numbers). The front pads are less easy to identify but very likely that OE are Jurid 571873J-AS as sold by C3BMW here:

http://www.ebay.co.uk/itm/BMW-E39-M5-FRONT-PADS-SE...

They come with a wear sensor from C3BMW and the deal can be a little cheaper if you contact Simon at C3BMW directly. It's a very good price. Just make sure they are 571873J-AS, not the 571873J - they're the same size etc but a different compound. (I've got Ferodo DS2500 on the front axle of mine at the moment but will be fitting the Jurids when the time comes...be interesting to compare.)

Brake pads are a very personal choice amongst M5 owners and everyone has a different perspective...so you pays your money and makes your choice.

What a helpful response, thank you.

I was wondering how you rated the DS2500 pads on the E39 M5 (I have used them previously in a Renaultsport Megane 225 Trophy and they transformed the braking, great pedal feel and fade free braking for road use) I had been previously advised that Ferodo do not sell these pads for the M5! Why are you swopping the Ferodo for the Jurids?

Jamoor has said only one company makes them, not sure where he got the information though?

Delivery was 20 euros. I was £275 all in including a transaction fee from my bank due to different currency.

I've always been happy enough with the brakes for road use so not bothering with any 'upgraded' pads. I've ordered ATE pads from carpart4less- I seriously doubt there's anything between the likes of them and textar, jurid and pagid.

Someone bought Pagid branded discs from ECP and they turned out to be the ATE discs, so I'd suspect any discs on the market are likely to be ate.
I used brembo pads on mine, part number

Thanks for all responses.

The German brake supplier is currently out of stock, I have a rather amusing German email from them (which I translated using our friend Google Translate).

I have asked them to contact me again, when they have stock.

Pretty sure I got one of the last discs. 'Available' quantity was 1 at the time and I did think I'd better get them now as who knows when they'll be back in stock.

Next day I noticed there was more in stock but that obviously wasn't the case as Depthhoar found out.

Your German must be better than mine! Are their any meets planned for M5s in Surrey/South East? Trying to sort out insurance, Admiral Multicar is not proving very competitive this time round! (£360 for 11 months fully comp on a limited mileage, SD&P policy) Im 35, so no spring chicken!

Chrome automatically translates the page, it's not perfect but enough to get the information across.

Have you tried Aviva? Come the start of next month my annual policy is down to £360 at 26 with 6 years NCB and it's a daily driver.

As above, definitely Ferodo and available in the US but not widely available in the UK (Google the part number shown on the photo).

Absolutely no complaints about stopping power for fast road use even after multiple hard stops. Great feel & bite and only a little more dust than anticipated - not that dust concerns me since it washes off. Also have braided hoses which helps a little, too.

Anyway, bought the Jurids because they were/are a stunning deal compared to OE from the dealer but will only be fitted to the car when the Ferodos are near the wear limit, which isn't any time soon.

Apologies if my post is against the grain in the thinking of the thread but I ended up replacing my front brakes well before they needed to be (life wise) and I had no hesitation in going down the upgrading route, ending up with K-Sports 8pot kit with DS2500 pads and braided flexi lines - completely transformed my brakes into something that gave me confidence in actually being able to stop the car! That kit was also almost half the price of the similar AP Racing upgrade kit...

I thought the general consensus was that the standard brakes were terrible and they were among the first thing for owners to upgrade (same with the similar aged E46 M3?). But going by this thread, has that thinking changed and that you guys are happy with the braking performance of the standard brake set up?

PS I thought I got the info about upgrading from here but thinking about it I may have been reading the M5board forum at the time!

Don't the USA brakes differ from EUR versions?

Define 'upgrade' is the problem most people have. If the only issue is brake fade then you don't need to upgrade the calipers or discs, just the pads and fluid. Also for a number of kits the brake discs are actually a downgrade from the M5 EU OEM discs in terms of size or thickness so it depends on the kit and whether the only benefit is pad area on the disc and whether that's necessary. There are also issues if you just upgrade the front that you may screw up brake balance. After reading all of the potential issues I went with OEM discs, RS29 pads, upgraded fluid and stainless hoses all round and don't regret it at all. Haven't had fade or brake issues once since.
