[Es2] Big Brakes

Most of us are not posers on this list; takes too much work to do the
project in the first place.
I've driven the coupe and other 20v cars on the track, high speed
braking from 115 mph, and the G60s do fine, no fading, etc.  Big brakes
don't really do too much except allow repeated stops from high speed
without increased fade.  You might stop a bit faster, and the brake
pedal might be firmer, etc.  But those are the biggest brakes that Audi
used in the USA through the mid '90s, on a small platform car.  

The G60s are pretty heavy; probably not a big weight difference from the
Porsche brakes.  One option I might consider is a two-piece rotor and
lighter wheels; less unsprung weight would improve road feel.

I am fairly sure I can get the parts for $1k or less with some keen
I'm not a poser so I will not spend $ to fill up the empty space in my
wheels.  I will however spend it to make the car stop better.
100mph on the road is the same as 100 mph on the track so good brakes
are important everywhere.
