I had OEM shocks and Sportlines fitted when I bought my Ed. 30. I felt the car to be too harsh and bumpy going over even small creases. That's comparing with my GT Sport with Koni FSD, Eibach Pro-Kit, SuperPro ALK and the same sway bars as a GTI. The GT Sport was much more planted to the road and gave me a lot more confidence doing fast corners.
Sorted the problem with Koni Sport dampers, H&R -30 mm springs, SuperPro ALK and H&R sway bars. The car now turns really well and it's only harsh over much bigger creases.
If you hit a small bump in the road it was easy for the rear to hop a bit and mid corner that can be really dangerous.
I don't know how the Pirelli P-Zero are when half worn, the Eagle F1s Asys 2 handle well even when they're at the end of their life.
I'm glad you're ok and I hope you can have your car back on the road soon.
