aerodynamic improvements
I thought I'd compile all the aero mods I've done to my car into one thread.
grille block tried 90% but backed that down to 80% https://www.fuelly.com/attachments/fo...271813d705.jpg I tried Vortex generators but have found they were causing more drag than they were fixing so they came off. front tray and wheel dams https://www.fuelly.com/attachments/fo...083179155d.jpg https://www.fuelly.com/attachments/fo...2ad583f51d.jpg rear diffuser https://www.fuelly.com/attachments/fo...3fad14d698.jpg roof rack delete https://www.fuelly.com/attachments/fo...52570f5c13.jpg foam gap filler the interior is much quieter. https://www.fuelly.com/attachments/fo...eb1135f3cb.jpg Passenger side mirror delete (don't even miss it) https://www.fuelly.com/attachments/fo...a02710f5b7.jpg fog light covers (not tested yet but I think they will help a tiny bit) https://www.fuelly.com/attachments/fo...60c0029d73.jpg https://www.fuelly.com/attachments/fo...31ff3dc3fd.jpg |
That's inspiring. Now I want to do some long-forgotten under-tray and wheel air dam ideas. Your workmanship is way better than mine.
Why white for grille blocking? It would look ok if it was 100% coverage, but with holes it looks weird. Also, what's with the green string looking thing on the upper grille? What foam material did you use for the gap filler? |
how did you secure rear under tray @ the "far side" (the side closer to the center of the car)?
As well as the side that runs along side of the exhaust. Pics would be great! |
How did you determine the net benefit of the vortex generators? Seems daunting (well, to me anyway).
|
looks nice! i'd like to know what you used for your gap filling material, too. I'm suprised you haven't painted your hubcaps black to match everything else. Looks cool.

I used the green string to operate an experimental adjustable grill block... found it was a real PITA due to the curve of the grille. I used White coroplast because I was given a sheet by BEEF it is all painted black now.
My gap filler is standard Home store door weatherstrip foam. I would recommend finding something with a closed cell.... this stuff is a sponge the front tray is screwed to the frame and a skeleton mounted to the frame. I have since extended the tray to the back of the oil pan. The rear is screwed to the spare tire well and the frame as well as the bumper. I really would rather not have an all black car if I did there wouldn't be hubcaps. I kind of like these even over the original alloy wheels. |
I have a question for the wheel skirt users....
I have inner fender mounting bolts about 3/4 of the way down the opening. Is any skirt better than no skirt or should I go ahead and cover as much as possible? |

I have not made my skirts yet but once payday rolls around I might. I'm also looking at a front splitter as a possible addition but I don't know how much benefit I'll se from that.
|
I keep looking at your picture trying to spot the new addition and then remembering it's part of your signature!
How did you adjustable grille block work anyway? I can't see from the picture how you guide the movable bit. |
