Stick with 19s, they look awesome, and as stated before, get them refurbished as and when.
Fifty you're "famous" (for want of a better word:011: ) for them wheels, i always know it's you on other forums etc, i'm sure i'm not the only one to recognise you from them wheels alone. So i say keep 'em on!!
8.5 all round with 10mm front spacer and 15mm rear spacer. I need to run spacers on the front otherwise the wheels rub against the coilover strut but the other problem is they currently graze the arch liner and the arch lip when going over large bumps because with the spacers they are so wide they dont go up into the arch they hit the arch instead if you follow me.
