lol....yes, curves are almost always rated lower than an 'average' car can safely take them (safety factor); now, 100 mph, well that's pushing it /ubbthreads/images/graemlins/grin.gif
The only thing I don't like about the 4WS is in long curves, it makes the rear 'feel' like it wants to move around, although it's more of a feeling than the car actually doing anything. and yeah, making quick lane changes, it can be felt (as compared to a regular car)...
I will keep mine, even if I go to a 4-bolt someday. This car is not a competition vehicle for me, and I kind of like the feature, whether it's marketing ploy, or not. Just another thing that is special to these and, although mine is modified quite extensively, I like to keep everything intact and functional (even the ice cold A/C and ABS).
