One thing to keep in mind, is that this is not a kit designed for the LGT. It's the 08+ WRX kit, sold for the LGT.
I'll be doing my install at some point eventually, so I'll try and improve the instructions for an LGT/OBXT install.
The comment on IP&T's site about some 05-07's being able to keep the fogs is right on. I've seen the install on an one that kept the lights, and yours didn't.
