OK, twist my arm...  I do believe the cones were spaced at 100ft.  My car ('87
4kcsq) had 195/55-14 Dunlop SP8000's on the stock 14x6 rims.  A controlled run
would be at about 65 mph.  I think I went as fast as 70 mph, but was beginning
to loose control.  The reason being that the car was basically drifting (or
sliding - no torsen talk necessary on this gen-I quattro system) from side to
side between the cones.  I guess that coupled with the excessive body roll would
give the impression that the car was about to 'swap ends', but was actually
quite predictable.  The tricky part was timing the steering wheel inputs so that
the car would have the appropriate attitude going thru the cones.  There was a
measurable lag form the time I made a change to when the car reacted.  Perhaps
those differential equation courses I took in college are usefull for something
after all ;) 

Given that Jason had some good sway bars and R1's on his A4, I do believe he was
capable of going at least 75 mph.
