BWAHAHAHAHA

What Do They Do?
# Reduce Overall Aerodynamic Drag
# Reduce Rear-end Air Flow Separation
# Reduce Turbulent Air Flow
# Allows For Faster Clean Air at Rear End


What Does This Mean?
# Increased Gas Mileage
# Increased Performance
# Increased Down Force
# Increased Top Speed
# Increased Velocity

 

If you place them a little closer together you could cut french fries with the roof of your 8. They could also be usefull if you have a problem with pigeons resting on your car.

 

only if they're in cf

 

The ? would be do they do anything at the speeds we can attain, wiith the aerodynamics we already have. Sure they work on planes and perhaps even brick-like big rigs and trailers, but.... inquiring minds would like to know... nice they were made expressly for the RX-8 though.

 

They don't do anything................ and they look horrible

 

Just what i wanted! a row of miniature shark fins for the roof! I'm sure with those on my ride people will get out of my way much faster!

/no I'm not serious

 

i ordered two sets. one for the roof, the other for my trunk.

maybe a third for the hood?

 

im gonna split my set 5 on each mirror

 

This is a theoretical analysis of VG's on sedans....
http://www.mitsubishi-motors.com/cor...004/16E_03.pdf

From their conclusions:
"(2) Application of the VGs of the optimum shape determined through the abovementioned analyses to the Mitsubishi LANCER EVOLUTION showed a 0.006 reduction in both the drag coefficient and lift coefficient."

0.006 is not a very large decrease in drag. As a general rule of thumb, a 0.01 change in the drag coefficient of a common domestic vehicle equates to a 0.1 to 0.2 MPG change in fuel efficiency. Of course, it depends on more variables than just the forward drag coefficient, but that'll get you in the ballpark. In other words, we're not talking about a very noticeable increase in fuel efficiency with the addition of VG's, even on the fuel-hungry RX-8. And... they look horrible.

 

might work on side mirror as well?

 

HP ftw!!

 

these are almost as worse as strakes. Haha

 

sweet, i just got a great idea! I'll put five of each on the fender vent! Its the new age strake!

 

Strakes aren't that bad. They make RX-8s look like Crossfires FTW!!!

 

i love making fun of strakes cause I have a set on my 8 too

 

^lol! at least you make fun of them through experience. i had them on my silver as well. lol. bryan doesn't have any experience with them. i bet somewhere in his head, he wants to try.

 

Vortex Generator sounds like a machine used by the army to create huge storms..... lol

I bet it's some top secret weapon.....

bryan knows about everything top secret.... with his super top secret mods and all

 

Nuuuuthin..........

 

I was about to say, if these are in Carbon Fiber my boy deedub will be all over them, he loves useless carbon stuff just like carbon battery covers and engine covers the weight savings adds ..00001 HP!

 

i would go for a rear diffuser before I went for these.

 

MY RX8 Is like sum Shark Fins..

(LL COO J.. my hat is like a sharks fin)

 

they would only work if they were custom made for the car, which i doubt anything on ebay is

 

Something like this is not going to work unless you're doing 300mph...... I'm not kidding....

 

actually at that speed they wouldn't work at all.

 

Maybe they should put a disclaimer?
