[s-cars] RS6

[Frederic L'Huillier]

Robin,

As for the brakes on fire, I have seen it on a stock RS6 during our
national event where the driver forgot to cool the brakes/engine after
hard laps. Black smoke on both front tires was coming from the calipers.
He had to do a couple of laps to avoid the brakes to go on fire ! ! ! !


I suppose you are talking about Movit. I understood they had already a
kit for the RS6.

Regards,
Frederic

Those rotors you admire are better used as boat anchors, or hose stands
in the dyno room. The design is ill executed. If you examine the rotors
you will see that there is no way that air can get into the centre of
the rotors to be centrifugally spun out, cooling the rotors on the way.
To add insult to injury, mounting the rotors on (13, from memory)
isolating pins, causes the heat to stay in the rotors. These rotors are
easily destroyed, the callipers selected by quattro GmbH don't help the
cause, either. The (expensive) 8 piston rotors are designed to use quite
small pads. This encourages hot spotting and even sets the pads on fire.
As the car is automatic, the pads are more frequently engaged than is
the case with a manual. Champion Racing learned all this when they first
started campaigning their RS6s. In truth, for high speed road use, I
mean up to 200 MPH, there is not a satisfactory solution presently
available. A major player in the brake business is having new thicker
rotors manufactured later this year, these will be 390-400 mm diameter
and 34 or 36 mm thick with very sophisticatedly shaped and profiled
inner vanes. Such cars as the Cayenne Turbo, the Bentley Continental GT
and their cousins have opened up the top end of the brake market - how
much will these cost, best not to ask, particularly with the dollar so
weak presently.
