.....  Let a drifter (ex-prorally) guy help ya out some here....  the 5ktq is
an interesting beast in that the car exibits lift throttle oversteer, neutral
throttle to mild throttle understeer, and WOT oversteer (assuming the car is
tweekd, if not, back to understeer)....  Control is key....  Might want to
reread my Steamboat post, boy did I play!!!.....  Eric is right on with the
loading, more specifically what he is talking about is shifting the pivot
point of the car, if you load a front heavy car with braking, your pivot
point is forward so understeer will be your enemy.....  do your braking IN A
STRAIGHT LINE, then turn, you try to trail brake an audi, you better be damn
good (and even then surprises happen, btdt).....  do NOT lock the rear diff,
you will understeer like a pig, and your control of the car, esp with a long
wheelbase 5ktq is NIL, BTTT (tried that) at steamboat, forget it, play with
the rear coming out of a turn for point and shoot, but to go into one with it
is just wrong, by definition....  First, mike, I might suggest evening up the
tire score, you are adding too much variance into the equation here.....
 5ktq's can prorally with the best of the best, done it, racing an ex-Shepard
Rally Colt (hunh?)....  The key is to get the car light on it's feet, which
may be an oxymoron with the q's but it can be done....  Then the rule is the
foot only goes in or stays steadi (your welcome), never let the foot back off
the gas, or you will be back to a big piggy understeering and ugly beast.....
 And to get it back might give you the median before the turn.... 
Forget the E-brake, that's cheating, sure it works, but any prorally
navigator (Bob?) will bonk you on the head for screwing up the correction on
the computer, and, you don't need to do it, you're missing the chassis
dynamics if you do anyhow....  Go into the turn late, turn hard, power on
oversteer, unwind that baby, it is THE quattro line, ck out Buffums book on
his quattro career it defines the q line.....
 I was just in an S6 with Mr. Wiles (ex prorally champ GTI) at the Grattan
event, and he slid that bad boy all the way around the track, without raising
a hair on my head.....  Eric and I can dance a q thru a turn pretty darn well
too, and the trick is the setup and the go pedal, minimal steering input....
 The fact that you have the understeer to oversteer condition and a fine line
inbetween means that if you can't do it, ride with one that can, these q's
can fly with proper piloting, No question......   BTDT still do that....
