Forgeline can now fit 19x11s all around. I prefer the true square to the semi square Z/28.
You can run the 305 setup with stock springs and shocks because the unsprung weight is reduced. You do get better results with the higher spring rates available if you go coilovers.
The HUGE benefit is a dramatic reduction in understeer from just the wheels and tires. Sways, bushes and coils are all plus add ons.
