Brake disk options

[rushey]

Morning all,

Well the dreaded brake pad warning light came on last week (they were 80-90% gone at the oil change) so assessing options.

I'm loving the car so won't be changing for a while but with 760 on tap I know I need an brake upgrade. I have quotes on the table (albeit without any bartering yet) for steelies at around 1500 a corner through to 15 bags for the muts nuts 'ramics. After speaking to Kim at MTM and he advised that many have gone for front 'ramics only as these obviously take the pounding.

Anyone heard of this ? I would welcome peoples thoughts / experiences / advice

Cheers

Just the front ceramics is only OK if funds are limited but you won't get the full on effect. I know this because I took that initial step.

If you opt for Ceramics then IMO the only way to go is the full setup. It is very expensive but boy is it worth every penny and a life saver if you do silly speeds.

a life saver is you do silly speeds.

Hi rushey,


I can't argue against ceramics for the front, but expensive with need for change to abs, master cylinder etc., I believe.

I have fitted the MTM 405mm steels, and they are very impressive.

Have been tested most recently at standing start 0-1000 metre sprint and pulled the beast up from 261 km/hr in less than 300 metres with confidence whereas previous year OEM 390 mm steels from only 250km/hr were a bit of "whoa nelly" to stop in 300 metres.
I can confirm that I did notice significant braking improvement with the 405 mm steel fronts over the OEM 390 mm fronts.

The 405 mm steels are also lighter than the oem 390mm and have improved cooling vane construction, at least according to Performance Friction, the manufacturers of the MTM rotors.

Our beasts are quite heavy and not really suited for serious track work.

Another forum member has tracked her RS6 Avant and ended up with cracks in her ceramics, a result of very high brake and heat loads. They were expensive to replace .

So I am sticking with my MTM - Performance Friction 405 mm steels on the front.

I know on lambos, steels and ceramics of equivalent size have same stopping distance.The only advantage that ceramics have over equivalent size steels is that ceramics last a lot longer.
However, on a mates GT3 Gallardo at our local track, the car runs 390 mm steels and they get a workout but don't fade. Rotor rings much, much cheaper to replace than ceramics. See pic from recent night event.

just my two cents worth.
cheers,

Cheers guys, I've just noticed the first MOT was due last week so need to sort

Classba, in what way did you "not get the full effect" Did the car feel unbalanced ? I drive hard but not lunatic stuff. Did Audi do your upgrade, did they have to mess with the ABS ?

Perth, I'll have a look at these and discuss with Kim. Did you fit yourself ? Any problems other than the pre requisite 20" wheels.

Also, I know I mentioned this before but the RS has started labouring again on start up. Seemed to go away after the oil change but yesterday it actually missed before spluttering into life.

Rushey hi, Don't get me wrong... just fitting the front Ceramics dramatically improves the breaking performance and it's only after I fitted the rears that I noticed the imbalance and how GREAT the full set up really is. Nothing else needs changing and only coding of the ABS is required. I did however changed all the rubber brake lines to stainless and flushed/changed the brake fluid to ATE super blue.

The Ceramics is a game changer for the 6 if you drive hard and IMO, no steel set up can come remotely close to it.

I got Virdee Autos in London to retrofit my set up.... give him a shout.

Cheers.

Hi rushey,

Classba is right. The ceramics are the ultimate. I think the comment that "no steel set up can come remotely close to it" is probably a bit boisterous.

However, as there are only 2 other RS6's in WA and none running ceramics, a bit hard for me to quote a real street result to provide absolute comparison.

MTM may be able to provide comparative braking results between ceramics and the 405 mm steels.

On the fitting of the MTM steels, I had my local indie Audi specialist fit. Same procedure and cost as changing oem rotors out. Labour charge of gbp 145. Seemed to me very reasonable compared to the gbp 500 charge from dealer.

cheers,

"Another forum member has tracked her RS6 Avant and ended up with cracks in her ceramics, a result of very high brake and heat loads. They were expensive to replace" .

I thought the whole idea of ceramics was higher speed braking and higher temperatures. Should they not cope better with this ?
I saw a C6 at QST a few weeks ago with ceramics, it had been on one track session and the discs were chipped and had cracks on them not very good for 15k me thinks

On the Porsche and Ferrari scene its very common to change out the Ceramics with steel for tracked cars....... My F430 has Ceramics, my 360 has steels, much less visible brake dust from the ceramics.. The biggest advantage.

So just to share my experience I actually opted for the standard steels in the end as told the rears were only 75% gone and driving around with no MOT whist awaiting new parts from Germany wasn't the answer. However when I went to collect from Macc Audi I was ushered to one side and some rather senior chap came out and explained that there "had been a problem sir" as they had inadvertently done both the front and rear swap, disposing of the offending items in the process, thus unable to put back to how it was. They already said they wouldn't charge me any labour on the fronts as compo for the screw up and as I hadn't authorised work on the rears they gave me two options

1) Just be charged the parts bill only or
2) Reject the work altogether and as my original disks had been binned accept the replacements gratis

Not a bad deal, £960 inc VAT for new disks and pads all round - I gave them a glowing report on the questionnaire

[skirs6]

That's a good deal. I think my fronts alone were best part of £1,200 might be worth making the journey to Macc Audi and hope they mess up !!!!!!
