I didn't actually do the conversion myself. Another member who's already posting in this thread, @
Acree is the guy responsible. He's done conversions on over 50 different vehicles and mine was the first BRZ that he got his hands on.
It's a pretty intensive process to tackle the whole project, but I'll let him chime in with what he plans to do with regards to a write up, as well as DIY kits, and retrofitting services.
