Couple of responses:

BoosTDIt: Yes, the R32 has the TT Spindles, but it also has a fully independent rear suspension that provides better camber characteristics than the other VW A4s. Also, the TTFWD, IIRC, was the car that was causing problems for the German drivers, and I think that car had the same rear suspension as our VWs.

Cielidh: I have to wonder if the transition to terminal understeer would be as dramatic as you stated. If you look at Peter's chart above, and charts in the Suspension Geometry FAQ on Vortex, all the spindles (TT, H2, stock) transition to positive camber, just at different degrees of roll. What's hard to gauge is how that curve feels behind the wheel: what looks like a progressive transition my be experienced as very abrupt.

So what's ideal? A setup where the front and rear lose traction at the same time? Or very mild terminal understeer/oversteer? And how can we set our cars up for that?

It seems that the VW stock opton of a gradual transition to terminal understeer (plenty of warning) is safest. It just isn't a lot of fun because the cornering limits are lower.
