DO we know why Koni suggests not to use FSD with lowered spring? I guess M030 or factory sports springs are OK (my SAAB uses OEM Aero springs), but wondering if any issues with H&R on my Boxster like with 30-40mm lowered from stock.

Koni FSD is approved with Eibach Pro Kit lowering springs for Boxster (not made by Eibach for USA anymore but still made for overseas) - I don't have the specs for those springs but if someone could find them and compare to H&R and the other lowering springs, they would probably be very similar and would work.

I personally run the Koni FSD with USA m030 springs so I don't have any info about lowering unfortunately.
