By the way, until we see some part numbers, I'm also assuming that the ZCP package is running this same Edition/Japanese suspension setup.
Here's that thread:
Your assumption is correct.
The Competition package does use new 10mm lower springs and
new re-valved EDC shocks/struts. (including revised EDC programming)
