Thanks for the concern guys.
To answer some questions:
1) Yes, it is the UAM CF Amuse kit
2) Could be hydroplane, also I'm still rockin my stock tires at 25k
and I was in the process of having a set of RE-11 installed.
3) Mostly cosmetic damage, I'm just worried about the axle, toe kit, suspension and the loud hissing noise from the engine bay.
I'll keep everyone posted for updates. If the car needs replacement depending on my insurance's decision, the replacement most likely wont be a Z34 anymore.
What spooks me the most was I was going 55mph, and the bags didn't even bother deploying...
