[s-cars] UrS as a Purpose Built Track Car?

[Calvin Craig]

OK, I know they weigh a ton, well two to be exact, and I know they have been
dogged on as crappy track cars.  Let me explain my reasoning.

I have a very well sorted B5 S4 with lots of great mods on it and the thing
does very well at the track.  However, it is my daily driver and a very
sweet ride and I don't want to ruin it by taking it to the track as much as
I really want to.

I really would like to stick with an AWD track car.  I have a '92 S4 that my
nephew has been driving through college and will be giving up next winter
when he graduates.  I have owned it 10 years now.  It is in pretty rough
shape from a body and interior perspective but it still runs great after
over 200k miles total and 100k miles peaking out at 21 psi :)

The plan would be to strip it down to bare bones and get all the weight out
of it that I can.  Then put some suspension goodies like 2B coilovers and a
good brake kit on it.

My question is, how much weight can you get out of it by going on a ruthless
diet?  Is this just a stupid idea?
