For those of you who remember the winner of the 2014 Scion FR-S Tuner Challange, the Speedhunters entry, you may also recall it had a sweet one-off rear diffuser. Well, it looks like they're finally putting it into production. See the article
here. It's available for sale
here.
I am in no way affiliated with Charvonia or Speedhunters, but I was inspired by the design when I first saw it. I love that it does away with the stock muffler, backup/fog light and the entire diffuser facade in order to increase the expansion angle. Assuming the angle isn't too steep-- hard to tell about that without testing-- it could potentially create more down-force than the lower slung diffusers from Velox, Driveway Labs, et al. Again, that's assuming the angle isn't so steep that it stalls. It probably needs some panels forward of the axle to smooth out the flow, too. And the overhang seems a little short... but hey, it looks good!
Anyway, just thought I'd get the ball rolling on the discussion here. I don't plan to buy it, but I can't wait to see pics from anybody that does.
