Search is letting me down, I'm not finding details for the install. Has anybody on here done it? Simple swap less reinforcement or are additional parts and fab needed like the 2nd Gen?

 

You will need the front fenders, core support, headlights, hood, and all bumper brackets, reinforcements, and some under hood accessories that got moved around. Not including some minor fab work to get the parts to fit. The JDM Fit has a much shorter front end than the ones here in the US. Hence why the JDM hoods don't fit US spec cars. They are much shorter in length.

JDM rear bumper bolts on very easily. The front needs a ton of parts to convert and is not a simple parts swap. I know because I was going for the Mugen aero kit on my US 2018 Fit Sport through my buddies at King Motorsports. The costs were just not worth it for me. The authentic Mugen aero and OEM swap parts was well over $6,000. Plus shipping and a very long wait time. Hard pass for just a new look on my commuter car. lol

And also at this age Honda has already discontinued most of the 3rd generation parts as they has available the 4th gen Fit's now in Japan. So even finding all of the correct parts new through Honda will for sure be a challenge. Lots of stuff is already gone from dealerships over there. And they don't save parts at their dealerships like we do here in the US.

 

Yeah, that confirms what I saw comparing part numbers. Did a quick check and fenders, hood, front frame rails, and core support were all different numbers. Probably also confirms lack of detail on the net, nobody has done the swap.
