Those are from RX8Strakes.com and they're called Vortex Generator Fins. http://www.rx8strakes.com/index.asp?...PROD&ProdID=99
They are actually proven to work, surprisingly.

To bad their effect at freeway speeds is practically nothing.
There is a debate goin on over on the 7 forums about these.
They are great for a race car, but for commuting . . . . . . . .they are nothing more than ricer jewelry

I didn't notice a build..just stick-on stuff.
I'd seen it several times driving around - didn't notice the Vortext stuff till yesterday.
I appreciate their enthusiasm - a lot. My kar still looks st0ck, going on 4 years later.

Fwiw
This article is not about fins on an automotive application, but much/all of the science behind it still applies...
Common sense tells me that to even see minimal advantages under any conditions, the fins have to be placed fairly perfectly... you cant just go stick some fins on so they look straight and get the same current eddy effect.

Vortex generators
A wind turbine blade does not have the same aerodynamic efficiency along its entire length. Towards the root, thick airfoils are used to enable the blade to bear its own weight. The blade is circular at this end, to permit mounting on the turbine. These factors have a negative effect on the blade’s performance.
Vortex generators consist of a number of small fins that protrude over the interface that occurs when the wind moves over the surface. These fins are mounted opposite each other at a certain angle that causes counter-current eddies in the air flow.
Vortex generators result in the flow of air subsequently separating from the surface at a later point, i.e. at higher wind speeds. This delays the moment when the blades stall and thus lose their capacity to produce power – the lowest part of the blade is thus efficient during a greater part of the turbine’s production time.
Vortex generators can boost blade performance by up to 4–6
