1997-1998 front end options LIP vs. Silvia bumper

I was thinking of getting the front lip for my 98 240sx that makes the car look more aggressive. I saw it on Habu's car domain site and it looks very nice. He also said miles per gallon improved because it makes the car more areo dynamic which is definetly a plus for me because most of the driving I do is a constant 60-80mph. Anyways, I'm also considering getting the bumper that came on the 97-98 Silvias in Japan. How low does this bumper go? Will I see advantages in areodynamics like with the lip for the USDM bumper? I'm guessing its equal to the USDM bumper, just different turn signals. I want to go this route because my current bumper has deep scratches in it, and ever time I wax I have to avoid the bumper because the wax stays in the cracks so I'll need to replace it anyway.

If I replace my bumper, what else do I need to do to the exterior to make it look like a Silvia? I'm going to get a replica spec K wing, the S sheild for the hood, and "Silvia" to replace 240sx.

Also, what am I looking at spending for a Silvia bumper swap? I've seen them go for $200 - $800. Why a huge gap?

demand at the time has alot to do with price of parts like that bumper.

is there a spoiler for the silvia bumper or is it low enough?

I am also interested in this. I was thinking of getting a front lip but I got quoted $300 + shipping and with that money, I could just get a Silvia 97-98 bumper.

A used jdm kouki bumper will be ~$600 in good condition. There was an optional aero front spoiler but its rare and really expensive.
