I thought we had already established that the main reason for upgrading to
11" brakes was their ability to stop faster from higher speeds or in
situations where tire traction is better-than-stock.

Ever compared an 11" rotor to a 10.1" rotor?  The difference is minimal..
we're talking about maybe 3/4lb. per rotor.  I'm not so sure how much
heavier Corrado calipers are, but I imagine it's maybe 2 or 3lb per side.

Define "oodles", please :)

Who gives a crap about tight autox courses... that might be the *one*
instance where you'd actually notice the disadvantages of 11" rotors.  And
how many Scirocco owners actually autox?  Sure, there's a lot on this list
but I have a feeling this list is a pretty skewed sample of Scirocco owners
worldwide.

My eyesight isn't so good.... but even so, I'm pretty sure I don't see an
"IMHO" associated with that claim... :)
