so i was reading up on the toyota prius the other day and i found out it has flat bottom panels to increase aerodynamics. well, why not do it to the tC? i know what the bottom of my car looks like and there seem to be air pockets everywhere! esp around the rear bumper.

has anyone done/bought/installed such a thing yet? ive done some research but couldnt find it anywhere... perhaps im using the wrong search words?

i thought i'd ask before i go ahead with my cardboard/duct tape ;)

 

I understand what you are saying. The prius is like a small mini van to me and probably needs help with aerodynamics. The tc is pretty aerodynamic IMO. What do you use your car for? Track ,auto x, or just street. I can't see a need for that on a DD..

 

Sadly its been discussed and we have tried to get them made by many aftermarket companies but nothing yet!

 

won't a DD car need it the most? depending on the distance of the commute, i can imagine using flat bottom panels on the freeway can save mucho gas due to higher speeds?

 

my buddy and i are in the works of making our own. He made his own for a S2k and it came out real clean. We are just using sheet metal from home depot, We should begin working on it within the next week and I will post up progress pics when possible

 

actually, the prius has a pretty good drag coefficient, with or without the flat bottom panels. i guess every little bit helps efficiency.

as for me, im planning to do this to my DD, just because im interested and i want to. in theory it should help my mpg and increase performance... def a win-win if you ask me. and if it doesnt work, its all good as i have nothing to lose, really.

dude thats awesome! i never thought about using sheet metal.. nor did i realize i had access to it. well keep me updated man, im def trying that in the near future! perhaps if you come up with something legit, you could even sell them as a kit

 

thats cool man post some pics when u finish it

 

a while ago we tried to get this developed: https://www.scionlife.com/forums/sho...d.php?t=129450

but if my memory serves me right, there weren't enough buyers willing to put down their money.

 

^^ agreed. I would like to see it when finished, maybe you'll convince me 2 do mine.lol

 

man thats a bummer... i guess no updates since then? for a $180 i would def get that.. even though i'd add on to cover the entire bottom.

ive found some home made ones on a honda forum:




not a bad job at all if you ask me. i'd personally make it a bit neater, and have the area covered before the rear diffuser.. but still impressive nonetheless. i think this will be my winter project once i get my car back.

edit: btw i live just a few miles away from you... gaithersburg here around the kentlands area. you have any pics of your car? might have ran into you a few times ;)

 

would be interesting to see actual testing to determine whether it helps or not

 

x2.. the edges look really rough lol i tried to reboot this project with kamispeed a few months ago (since it's been forever since the original thread was created) but i don't think they're really interested in producing it

viper sir, u've got a PM

yellow, they've did some testing with the evo. no hard evidence was shown that these underpanels helped with turbulence/aerodynamics/cooling but they've sworn it helped with the lap times.. here are the threads:

in theory they work, in lap times they work (though better driving/other factors could've EASILY made that faster lap time). im gonna make a mock up during winter break just for the hell of it =P

 

i dont see it helping too much, performance wise, but if it helps my gas economy that would be great

 

Just to keep everyone updated, My friend and I have officially started this project. So far I spent a $22.96 on materials needed. Going to get things measured and cut this weekend and hopefully get pictures up as we go along.

 

In for pics, my buddy did one in the rear and said it helped the stability a bunch at highways speeds.

 

I always wanted one since pete did that.

 

watching

 

i'm interested in seeing how this goes. anyone have pictures of pete's project?

 

^I will see if he can post something up. I priced out some 1/8" rigid abs at about $45 to make something similar to the back plus hardware, etc.

 

yea i started to do this when i lost my engine covers and talked to dr iso about it because he did the splitter and i bought a sheet of abs i think 3/16 or 1/8 and got it cut out just havent got around to mounting. this thread kinda sparked my interest to get it done though
