New Wheels + Lowering??

[me..me..me]

Hi All
Another wheel question!!
I have a 2013 Cali ready for tyres so looking at upgrades from the standard 17" wheel. I would like to either go -30mm Sportline or Bilstein B14 and 19" or 20" to lower a bit for ride and asthetics improvement (in my opinion!) I'm looking at :-
19/20" x 8.5" front with around a 35mm offset and
19/20" x 9" rear with around a 40mm offset (trying to clear the Cali Door lining)
Could anyone who has done any of these mods put some photos on of 19' fit and 20" fit for asthetics please?
Anyone have much experience of the Bilstein B14s and the ride quality?
I know that this isn't purest and may create further issues so this is a fact find and I would welcome a wide range of views / experience from you guys......
Thanks in advance
