p11 wagon side skirts, rear bumper lip, do they fit sedans?

yes they do. i have them but have not installed them...

Everything will work as long as you have $$$. If you are looking to just put it on the usdm rear bumper my guess is that it will not fit. The reason is because wagon rear bumpers are bigger/wider. As for those skirts they are IMPUL skirts if im not mistaken. If they are they are very hard to come across. Ive been on the forum since 06 and have only seen them pop up once here and I bought them. Lol

The wagon rear-side bumper skirts things are a bit of a pain to fit but not impossible. The lip on the other hand...I think that would take a lot of custom work.

I did some research and the p11 sedan and wagon share the same exact wheelbase at 2600mm. So Im pretty sure they will fit with minor or no mods.

I have a feeling the rear lip will also fit because wagon bumpers are longer than JDM sedans and the US bumper is longer than JDM one. Reason why wagon nismo of fujitsubo mufflers work fine on us sedans.

Cal (Aloha20t) was trying to fit the rear lip to a usdm bumper. You might want to reach out to him to see how close of a fit it is.

I see you've done good research and what you said is all correct regarding the mufflers and wheelbase and all that, but for some reason they are not the same shape. When I tried to install the bumper skirts on the sides on my 2002 bumper it was way off and took a lot of cutting and bending and heating to get it to even follow the curve at all. The mounting points are also completely different...I would say they were as "bolt on" as a pair of skirts off an Accord or Skyline sedan would be. I wish you luck, but don't be surprised when it's more work than you thought! (I hope I'm wrong but I don't see how I can be.)

Would P11-144 rear valances fit on a g20 sedan without any issues?
