[s-cars] Brake Pedal to the floor w/ ECS Stage II and Rear Slotted

[QSHIPQ at aol.com]

Yup, I'm with you and Leigh on this Keith.  If you believe the audi SAE
articles, the front heavy quattros weight shift under maximum braking of 80%f/20%r
pretty much model wide (and in fact, the S car is one of the worst in this
respect).  Which means that if you took a set of stock brakes, the front 2 brake
are handling 3080lbs of load, and the rears are handling 720lbs of load.  The
stock rears are plenty for that, especially if you consider that a wheel/tire
upgrade (mit big reds) means even more weight shift forward.

I say put the most agressive pad in the rear (especially the 4 channel abs
cars), and cad plate the rotor to keep the fins clean longer, and call it good.
Rear BR may have you in the looks department, but certainly in terms of
performance, I really doubt any better measures would result from what's already on
the car.  IME with big rears on the type 44tq with locking diff, you get
better rear life and "feel" because of the fixed caliper arrangement, but that's
about it.

No one will look better rolling down the road tho, Hap!

On a semi-related topic, I'm with Leigh on the Big-Rear-Brakes - completely
unecessary for performance.  I find my UrS4 (ECS Stage II at front) to be
almost over-braked at the rear.  If you have even larger front rotors, then it's
possible you need to bias more brakes to the rear, but in this case I'm pretty
sure a adjustable bias valve will give you all the extra rear braking power you
need, much cheaper than Big Reds and the associated parking brake hassles.
They do look good though :-)
