Great write up and videos! Thanks so much for sharing. This is the real world feedback that we need more of on this forum.
Keep up the good work
PS. I changed the standard suspension on my old 987 to H&R cup coil-overs and had it properly aligned. Like day and night. It did not ride much harsher, but handled like a go cart. Look into the roll-bars as well. The standard ones are probably too soft for PSS10. I switched mine to H&R too.
