Unless your planning on doing track days I would probably suggest upgrading to PP spec using VAG stuff.
That way you will retain the OEM look whilst being an improvement over your non PP setup.
Also, some of these aftermarket mods could deter a potential buyer if you decide to sell in future, whereas an upgrade to PP spec could be viewed as a nice improvement.
Anything I've ever done like this is fully reversible so i can return back to standard.
