Hey!
I have a 2016 base model Lexus is200t and i’m trying to do the bumper conversion from the Non fsport bumper to the nicer Fsport front bumper.
Ofc I know I need the main piece which is the bumper itself and the fsport front grille but what else do I need? does anyone have a list of parts that are assembled with the bumper? Or any part numbers?

Example:

 

Gonna keep an eye on this thread as I'm doing the exact same thing. Only things I already have right now as "necessary" are: bumper, grille. side ducts, inner ducts, tow hook cover. I'm mainly curious if there are any brackets or anything in general for the backside that is necessary.
