You never brake on the Autobahn and RS4 is not suited for the racetrack.
Do you talk bo11ox alot?

That's funny :D

I've had to brake many times on the Autobahn & agree the RS4 is never going to be a track animal, but i've had great fun & results on track days in my M5 & before that the RS6 (better in the M5 as i increased my skill level with alot of track tuition). The M5 is less suited to track work than the RS4, as seen by the Nurburgring times etc as the RS4 is only 1 second slower than a CSL.

So RS4 is not perfect for the racetrack but it's behaviour on track is meant to be very good for the style of car & certainly capable. I'll report back after doing Scuderia in mine & over a week of Ring driving in September.

Be sure, you WILL brake when your car goes beyond 165mph and Grandpa Olaf needs the left lane for his awesome 80mph speed Passat :)
Not a racetrack car, but fast enough to play with the M3s and spend some lee to pull them along a straight line :D

But in this instance, wouldn't you be better to have non-ceramic brakes?

Racing in a straight line... An old Corvette can probably hand with a Ferrari then. Doesn't mean anything.

Every Racetrack has straight lines ... I need to pull them on the straight becausse they are just to underpowered to follow me without lee ... hey Dude, think about reality ... I drove a 1:45,8sec while a CSL does the same track same day 1:45,3sec (impressive ... what 500kg less weight can prove on the track ... :sigh:) ... ... and a 997C2S had 1:47,1sec ... only a 997GT3 had roundabout 1:42,0sec driven by an expert ... blame the others who cant control a RWD on the track.

On any motorway there is always some muppet who overtakes in a blind/suicidal way, and if you have ever driven in Southern Europe you will know that you NEED good braking power!

In fact from I have read the Carbon/ceramic type brakes are excellent when braking for any reason/speed and just get better and better the harder you brake, cause they work even better at higher temps.

I think Porsche only claimed 100k miles and look what happened there, there now no longer claim lifespan or even better stopping, just greater fade resistance and unsprung weight advantage

anyone know who makes Audi ceramics and whether they are the same technology as Porsche?

Brake caliper: Brembo M6 Al / Item no. 1LW
3 piston Monoblock each side of the disc (6 pistons total/side) with 32/36/38mm pistons
Discs: 380x38mm 5/112 punched, also BREMBO manufactured

Looks like the same system is used on Porsche, Ferrari etc., maybe some special components added at the higher priced discs. Ferrari front costs 12K EUR front, Audi about 7k EUR for boith front discs.

agreed however I am not convinced ceramic outperforms steels on the first 2 or 3 times this happens, ceramics have better fade resistance but if you are emergency braking continually for this reason them IMHO its your driving thats the problem, ie lack of anticipation / leaving sufficient space/time.

If they were offered for no or minimal cost I would spec them but the benefits for normal / road use are a) no brake dust and b) reduced unsprung weight and the ride/handling benefits that come with it, rather than material performance improvements.

IMHO

Well it is to good hear your opinion, well at least until you go on about my driving anyway!

As you obviously seem to have a lot of skill, this must stem from some great amount of experience in using ceramic brakes?

Well fair enough your opinion is "valid" even though there are fellow members who have expressed their personal experiences (real ones) and I think that they were more than sufficient, again thank you for non-constructive blurt.
