I would agree with a global increase in rebound rates, with probably not much increase in compression rates...at least to start. In theory, the rebound damping controls the sprung mass whereas the compression damping controls the unsprung mass. So the spring rates should only affect the rebound damping needs. That's on paper, and I would guess it applies more to high-speed damping than low-speed damping. So maybe a global increase in high/low-speed rebound and just low-speed compression?

Ideally, I'm thinking of something in between SLE and ZLE rates, maybe slightly closer to ZLE. It would be a pretty large change overall but right now the car is a bit soft and overdamped in track mode. It is amazing how well it works, GM's damping is really good but compromised for a smooth ride.

I agree with this, too. That would plug a big gap in the aftermarket.
