I don't trust you. Post evidence please.

I have a Beatrush front underpanel and I can feel and see a difference with that at highway speeds; better front end stability and better gas mileage.

I believe a rear diffuser would make a difference, particularly on a car with a big flat back end like the Fit has. It would help break up the airflow as it comes out from under the car (that's why it's called a diffuser, after all) and should reduce the suction effect back there.

I've been considering a homebuilt one as have a few other folks here, just haven't gotten the round tuit yet.

Yea, it's sexy without a doubt and j's used it to help with a lil aero on the track so if they have a reason to use it...definitely can't be harmful lol. I thought if you did anything jdm relating to the body it all had to be changed though? hood, bumper, 1/4 panels, bumper, sideskirts...or is that just with the front end?

the rear just requires a jdm rear bumper and rear crash bar. the side skirts just match the rest of the conversion. the front is the expensive part.

Chris, it looks like the Noblesse diffuser would cover up the rear jacking point. Does it, and if so, how do you deal with that? Thanks!

You do know that having aero parts decreases gas mileage right? I road race and have friends who compete in Time Attack events. I trust in their knowledge since they know wassup since they actually put their aero parts to use. I'm guessing aero parts would help a little, but not enough for the effort and money IMO.

that depends on what the aero part is.

If your talking about that big triangular piece then yes, that must be removed for the Diffuser. I never use that to jack anyway, I always use the towhook.
