Better brakes for the RS6

[Pelle75]

Is that possible? Of course see for yourself!

Those movit look nice but why would you want to change the audi 8 pot brakes for 6 pots??

Like the idea of 4 pots on the back though!

Hi

There are really good reasons for replacing the 8 piston calliper and rotor in front and ditching the rear brake set-up.

The 8 piston calliper has four very small pads, which easily overheat. Furthermore, the series rotor is designed in such a way that it is impossible for air to be forced into it.

Consequently, on production cars, the rotor hot spots, the pads catch fire, pad wear is dreadful and rotors get destroyed very easily. AMG uses the same calliper and has problems too.

The six piston calliper has twice the pad area of the 8 piston calliper and the 380mm rotors are properly ventilated, helped by some bodywork.

The production rear brakes are terrible and do very little work as the pads are incredibly hard in order to make the handbrake work.

Switching to a setup with a proper rear brake and a separate calliper for the rear brake removes the compromise inherent in the series design.

The car in the photograph had done a little more than 4,000 kilometres and there was only another 1,000 or so km left in the series pads, which are very expensive to replace. So be prepared for big brakem pad bills.

Another car, with about 1,500 km, has completed cooked rotors, quite blue, because of the poor ventilation. At no stage had this car ever brakes firmly enough to activate the ABS. Reviewing how it may have happened, there were three quite quick stops from 280kph to 100kph weithin a space of 10 minutes, thanks to idiots on the Autobahn at night.

So, two RS6s, both with serious brake shortcomings, pad wear and rotor cooking respectively.

I love the car, hate the brakes! As far as I am concerned, 500bhp totally transforms the car, at least that is what the MTM chip does, I cannot speak for other tuners.

Many Thanks for your informed reply...

suddenly me wants movit brakes , I too was suprised with the size of the rear calipers and agree that they don't do much..

do you feel that too much braking power at the rear of the car could cause the back to step out or would the ABS deal with that?

Thanks
Dave

Hi

The better rear brakes make the car feel more stable under retardation.

The 4-channel ABS will modulate each wheel individually.

Incidentally, when you feel the ABS start to activate, redouble the force on the brake pedal; the rear wheels, being unweighted under retardation have reached their limits of retardation/adhesion, the increased weight on the front wheels meands that there is still plenty of unused retardation capacity.

The increased thermal capacity of the rear brakes helps, especially in winter, when the EDL brakes the wheel that is slipping.

20" Sportec Wheels and 400 mm discs.

Brakes seem to cost 9590 Euro...

In the Sport Auto test they seem to be just a (very) little bit better than original.

Hi
The brake system I select is completely different to that which is sold by Sportec. Different manufacturers, different installation, different brake lines.

Good braking is not just about stopping distances, it embraces repeatability, reliability, low maintence, cost of disposables, pedal feel, performance in bad conditions and that 'feelgood factor' which gives you confidence to trust the brakes.

Like most of the good things in life, a really good brake system doesn't come cheap.

Hi Mate,

The old brain is starting to like these Movits.. have you got a price.. going to have the 500 MTM chip soon

Cheers

Send an email to g.frensemeyer@movit.de

Guido Frensemeyer is the boss and he will quote you a price. Tell him you have been talking to Robin.

Mov'it is located just across the Rhine from Strassbourg, so lots of good food and wine whilst you wait. MTM is about 3 hours drive further on, out the back of the Audi factory at Ingolstadt. depending on when you go, you could have the exhaust done as well.

Dave,
Robin is right in saying that the MoVit system will be your answer to your problems, i as you know have a full MoVit system on the RS4 and can verify that whilst i was in Germany, at Hockenheim and at Nordschlife i have a faultless performance in braking, also Guido is a very accomodating man, and very welcoming too, but if you dont want to go to Germany, Kim Collins can fit the brakes at the same time as fitting the MTM chip, also Miltek have just finished Mike Cheethams RS6 exhaust system and are now in a position to start "cat back " systems.

Very interesting discussion here.


Front



Rear. I guess the left caliper is for hand brake.

I guess the left caliper is for hand brake.

Its the very same on as mine and is taken from the Lamborghini Diablo system for the hand brake
Erik i agree a very interesting discussion.

John,

we must meet up for a chat soon.. so much I need to discuss with you..

MTM upgrade.. where to go and when...
Movit brakes.. where did you go and was it a good price?
Exhaust upgrades.. I'm also tempted to stick with MTM but did it upset your O2 sensors?

Cheers
Dave

[johneroberts]

Dave, cant see myselk getting down your way until next year now, but if your ever comming my way give me shout, only be too glad to oblige.
Kim Collins a Quattrosports did all the work and fitted the brakes, i can say pretty well know that its impossible to get a deal on MoVit, believe me i tried, Mike Cheetham is about to have the first set fitted to a RHD RS6 and the price is Scary £6-7K for full system.
Its pretty well know that on a RS6 you can only have a catsback system fitted due to the enormity of the job, 2 days engine out
The Miltek is by far the only option i would plumb for, as they have allready done 3-4 systems.
MTM is the only tuning company i would let near my car as they do seam to work closely with Audi de, and thats got to be worth somthing.
i will see you at Donnington no doubt on the 26th of Feb, im off there tomorrow to get some laps in before winter sets in.
Cheers

Thanks John,

If I'm ever up your way I will give you a shout. I had heard from Wolfgang at MTM in Germany about the problems fitting the new exhaust system.... Don't know how much power it is worth yet or the advanatges of paying for a two day job. And I'm not too sure that I want the engine taken out for a new exhaust system. Do you feel that it would be worth doing the cat backs???

Would be interested to know also if that chap is happy with his new movits.. 7K seems a lot to me.. I mean the standard setup is Ok to live with.. maybe it is something I will do further down the line when more systems have been fitted.

Already looking forward to Donnington..

Cheers
Dave

Movit has added new pictures of another RS6 on their website, including an image of the breakpads.

RS6-1


RS6-2


Difference in brake pad area:

Hi

I am delighted with the Mov'it brakes on both RS6s. Nice progressive feel and they just keep on doing their stuff, the way they are designed to do. Furthermore, they are much lighter than the stock system.

As far as the exhaust system goes, the MTM exhaust is not yet available, it is being developed right now.

The RS6s in the Mov'it photographs have quattro GmbH Sports exhausts. I can't compare the exhaust to stock, as both cars were fitted with them from new. In matt black it looks very good indeed and the sound is a beautiful burble.

Incidentally, do not confuse Miltek or Kim Collins exhausts with MTM exhausts, they are different, nor should the quattro GmbH Sports exhaust be confused with the Quaatro Sports (UK) exhaust, just to complicate matters!

I shall be at Essen on Press Preview day, if there are any questions. Email me off list for a treff.

FYI
MTM exhaust systems are now made by Scorpion, the were made and designed a while back by MiLteK
