Cool beans! I like the second from the last, where you make sure to "curl up" the leading edge of the rear to avoid a parachute effect.

Is that really coroplast or styrofoam? I was expecting to see plastic that was like cardboard :

Carlo,
it was at the store where I bought the choroplast. It's not styrafoam but harded, more rigid. Thd had a large scrap and I used it in the back and now the front.

Yes, the chorplast curved nicely to seal up the back area.

it looks like it might be a product called Foamex but I could be wrong (or something similar)

Infiniti

I like very much what you've done and I certainly don't want to discourage your efforts,but I wanted to point out that Nissan has done enough under car aerodynamic refinement on the Infiniti that they've published advertisements showing only the underside of the car.
Bottom line ( no pun ) is that you may not see gains,as say,you'd see on a Jeep,Land Cruiser,Rover,Tahoe,Suburban,etc..

Your refinements will put you in good stead for tail modifications should you choose to pursue that in the future.Nice work!

I gotta build me a bellypan! I'm contemplating either Coroplast, or aluminum flat bars & roll flashing...

Good job!

Actually, you are right a STOCK Q45 has some nice underbody panels that seal right up to the FACTORY bumper......

however, my situation is a little different.
I am running a Full IMPUL body kit which lowers the body lines 2 inches all the way around...



creating this.....



here was my dec thread describing my results....along with a blocked grille.
