04 Sentra Aeromods
Well, the first round of aeromods on my 2004 Nissan Sentra 1.8S are done. I've finished the full upper grille block, partial lower grille block, front underbody tray, front and rear tire spats, and partial rear underbody tray. Pics and write up below!
NOTE: I don't claim that the way that I did these mods is the best way, or even that great. It was just my method of doing it. Also, I cut and fit most these in the dark and I realized in the morning that some of them don't look very good up close, so I may redo them. Upper Grille Block:

I ran out of coroplast to finish the rear underbody tray completely, so that's my next project. This actually leads me to my question: should I make a new tray that extends to the part of the bumper directly behind the tire? You can see the area that I'm talking about on the left side of the picture below. http://imageshack.us/a/img607/6345/img1819lt.jpg Anyway, I hope this write up helps. Sorry for the length! |

For the lower grill block you could just trace out 1 giant piece and zip tie it on
The tray would be more aero sound if it was put inside the lip of the bumpers instead of below plus it would help support it better. |

I'll have to try moving the front tray from the outside to the inside of the bumper. I don't know why I didn't think of that when I made it... doh. |
the block being on the inside or outside definitely has been discussed b4
on one side it was said the outside would be better cuz of warm up and being traditionally aero designed on the other side putting the block on the inside was said to make a pocket of air to be trapped creating the outside block with the air that is unable to escape. On cars i see blocks as more of helping with warm up times than aero but a block no matter inside or out is more aero than a giant grill opening |

Also, I would show more data and A-B-A testing but I don't have my Ultragauge yet, so when I do I'll put up some real numbers. |

rear spat and rear gap
*the little voice in my head thinks that the rear tire spats will trigger flow separation which will overshoot the actual outer edge of the flap,leading to turbulence of such a degree that you'll risk re-attachment downstream.
If there's any way you could tuft that whole area and get a friend to watch,photograph,or videograph,you could see what's happening there. If you blended the spat into the rocker panel,as Subaru did with their 1986 XT (Cd 0.29) you could kill any turbulence formation. *As to the gap behind the rear wheels,yes,seal those areas,after checking out 'diffusers',which you might integrate into your design.These add a premium flow component to the wake area,and later,if you do any boat-tailing,it will pay you extra dividends.:) |

I'll set to work researching more about diffusers and rear aerodynamics. Thanks again for your help. |
Maybe you could try to boattail the wheel?
