or an early 90's honda prelude

 

Sounds costly & heavy. Not to mention it could turn out to be a reliability nightmare and a pain to keep all 4 wheels aligned properly.

 

The last time I saw 4wheel steering was that on a Honda 20yrs. ago. Now, I see the technology would finds its way into a Porsche! Which is very good thing!

 

are we talking about genuine 4 wheel steere or something like this torque vector stuff in the bmw x6 and so on?

 

They already came out with PTV, porsches version of torque vectoring. This is really a 4ws system.
All that I am upset about is that it wont be here for another 18months. How do they think we can wait that long. A year ago guys were wondering if they should get a 997.2TT or wait for the new one. That is a long ass wait.

 

Sure did, I had it on my 95 300zx TT back in the day.

[edit]

 

What's the point in 4WS? Maybe I'm missing the boat, but how does a tighter turning radius mean a faster time on the ring?

 

Agreed. Even if you did lose a half a second or so, you would just gain it back with the weight.

 

Everyone had these in my High School!
