like the 911 C4? It could be a worthwhile mod to partially adapt for the S4 front weight bias. Never heard of such a thing with Audi's so it may not be possible due to the differential type.

You can also tweak your tire pressure
or change tire sizes.
I'm not joking. I know it sounds silly, but you can change the force that the wheels give as input to the torsen, and it has the same effect.
tweaking pressure is not the long term fix, but it can give you a feel for it. You are basically reducing the traction of one end of the car, which obviously you don't want to do in the long run.
But then you get wider tires for the opposite end of the car, and you are increasing *it's* traction. And it's likelyhood of hydroplaning, so nothing's perfect.
Either way, you're not going to be able to adjust it on the fly. I think the porsche has a computer controled clutch, that's why it can be adjusted on the fly, you're just tuning the program.
You could theoretically do *that* with our ESP or even EDL.

yeah. get on a skid pad and play around with tire pressure.
it really lets you know how much a difference in tire pressure can make as far as the car pushing or getting loose around the skidpad.

The problem with that higher bias torsen is
that the more you split it, the more violent the torque shift is. This can present problems on high speed cornering when 62% of the torqe is sent to the opposite axle. UGLY.

Thanks for the replies - was more a curiosity. I love my car
and don't plan to mod extensively, but do sometimes miss the feel of my old RWD Porsche 968.

PS - first snow on the way and I haven't order winter wheels/tires yet. Time to get on it...winter has hit Rochester,NY!
