Looking at ETKA AQ was dropped on 2008 and AR used till 2013 for all engines so difference cannot be that big.
Looking at the sport suspension springs the same were used throughout all years PF and FL.
Shocks changed to CE(V6) and CD(V8 ) in 1999 chassis number 4D-X-000 001 but kept the same separate spring disc ( 8D0 412 103 B ) and underlay ( 4D0 412 107 B ) as PF until 2000 chassis no 4D-Y-020 000, CE was dropped in 2008 and CD used for all engines.
Then changed disc and underlay to single part( 8D0 412 066 F) from 2001 chassis number 4D0-1-000 001
Only way to find out for sure I guess is to try to fit them.
Looking at the pictures on the web PF shocks definitely have the ridge on which spring disc sits higher up but the disc is deeper so it brings the surface down. I don't know if I am reading ETKA wrong or what, or how they got away for 1 year using FL shocks with PF spring discs
?But looks like you will need PF spring discs and underlay to use PF shocks on FL car.
