mine is dropped 40mm, though I have no recent pics I can say that with a vr front splitter it sits just high enough to clear the square type speed bumps (the ones you can just get the tyres either side of) and scrapes ever so slightly when coming out of my works car park ramp, so I'd say if you want a daily driver that you dont need to worry about catching stuff on the 'great' British roads 40mm is the way to go
I run 16s with 45 profiles
Kit I have is a Wietec ultra GT and it drives like its on rails

getting a good quality kit is a must none of this £100 ebay coilover kit b0llocks
