There is no scion specific kit. Basically your gonna have to get a generic suicide door kit and have a body shop do the work. I have been tempted to do this but the expense and permanet nature of the mod keeps me from doing it.
The only thing I don't car for in the photo of it being shown is that he has it sitting on the factory Jack. That just looks so freakin cheap. If your gonna do all that work buy a custom looking jack or use the wheel stands that NoLiimitz sells.
