Oh, no, I haven't ever used PIAA bulbs. I was recommended a set off eBay by a member from SCN who had a good set (meant to be pure white), however I was sent a pair that was very yellow (more so than OEM bulbs!).
I am tempted by PIAA as they have good
reviews, but for the moment I guess my cheapy eBay blue-ish ones are okay. I think I have pictures of them somewhere in this thread.
The 'plus' nightbreakers are meant to be slightly whiter, apparently..
Not really sure about any more mods to be honest.. Still got a Cupra exhaust in my garage, which I suppose I could investigate this year.
I recently fitted my dead pedal/clutch rest metal plate the other week to finish off the footwell.
