Upside down damper. It's the one of the reasons I chose this kit:
Technically, it will allow me to slide where the strut nut is underneath the strut tower. Ignore the delrin spacers by the 3 nuts. They are only to protect the threads during transit and not to be used during install. I used the reinforcement ring to spread the load better and give little extra clearance to the dust cover but you could get away with out it too.
I think MCS started doing one too recently? Not sure. Most pics I see, are traditional non-inverted with the same "issue" or inconvenience etc. Anyway, you really do not want to pound the strut tower at such angles. I'm looking to move from -3.5 to -4 preferably with LCA/F8x TS etc.
