Makes all the difference in the world. Car now handles neutral on track.

Totally agree with
Vetracr - a stock E89 Z4 has a lot of rear camber compared to front. Maxing out front camber with Ground Control camber plates helps massively. To get even more camber, you need smaller springs = coilovers.
With camber plates (no rubber) and more camber you get increased tire wear and NVH though.
I tried putting the stock sway bar back in, while keeping the H&R rear sway bar on its stiffest settings. Yes it decreased under steer, and made the front feel lighter and softer, but it makes the car less responsive and more wobbly. I personally did not like it, and went back after one track session.
