No sleeve on the DDCs. Even though the install manual shows it. Took KW forever to answer that for me.
Just make sure you have the set screws set on the front coilovers when you set your height. The rest is pretty standard stuff for coils.
Went to Bimmer Invasion Orlando, got some car show trophies for the first time in my life, pretty crazy. Got to meet a few people fourm the forum too which was nice.
