I am using the APR GTC300 wing, bottom mount to the trunk lid. I like it, it looks good and based on the available CFD data it falls in-between the Hartman and 9LR wings. I have a homemade splitter mounted with Hartman kit. It obviously wouldn't produce the downforce of the Hartman CF piece, but replacing it after an off will hurt a lot less!! I used the pucks from professional awesome racing also. I also have dive planes and have vented the fenders.
