I was hell bent on getting a set of PSS10's for my R53 along with an AP BBK - unfortunately my shop in Hong Kong was shipped a set of PSS9s by mistake.

I understand there are some differences in the adjustability (positioning and number of levels on the adjustment for front shocks for example) but are there any significant mechanical differences between the sets of shocks?
I can negotiate them down on price for the PSS9s and will have to wait up to 8 weeks for the PSS10s so I'm leaning towards the 9s unless someone has any major benefits of the 10s they can point me to...

cheers, Paul.
