I'm liking the speedy progress on this! I used the FK's for a while. The only reason I took them off was the front didn't go mega low but they do give a decent drop still and ride fairly nicely. I went straight from KW V3 to the FK and for general day to day use the ride was fairly similar.
When I did my wrap I decided to get all new bumper and arch clips from BMW. The guy on parts said they would be about £30. When I picked them up I got slapped with a £75 bill. As you say they are so easy to work on. The wrap was such a simple job as all the trims and stuff just pop on and off.
