What is the PCW mod?
I do think the Valve remote is the other best way to go.. https://www.active-sound.eu/de/audi/audi-a4/audi-a4-8w/audi-rs4-8w-active-valve-control-klappensteuerung?action_ms=1
I have started looking at changing our B9 S4 Avant for a B9 RS4. Seems DRC is a rare option.
Keen to get views on the ride quality on 20's with or without?
Also if any one has compared it back to back, be great to hear views too.
Thanks!
