Message to argue, I feel that saying the best way to make a Z handle is keeping it at stock ride height flies in the face of 20+ years of real world experience with these cars (in general, not me personally) along with almost every magazine article ever written, suspension company's advice, etc. for various types of cars beyond a Z32. Yes, lowering your car may adversely affect roll center (depending on how low you go), but the small change in roll center is far outweighed by the massive improvement in handling, center of gravity, etc. that a lower stance and stiffer springs provide.

What does every aftermarket suspension company/magazine do when a new car comes out to make it handle better? Lower the car, and fit it with stiffer springs (and adjustable shocks). It's a time tested proven method.

Again, yes, roll center is affected, but if you lower a car right (and compensate through adjustable components to keep the alignment in spec), a Z32 will handle better/roll less than at stock ride height.

And what I was referring to about the horizontal axis not being negative was more for straight line issues while driving (bump steer, following the road, etc). If the LCA is not in the negative, the car will track straight and true even when lowered. Almost all cars will put the LCA negative (on one side) while cornering, even at stock ride height. That's just the nature of how a suspension works.
