Default Rear Bumper Air Diffuser

I found EOS rear bumper lower air diffuser fins in flat black on E-bay for $152.68 for 2 pair. The pictures appear to make it a nice looking and functional mod. I was wondering if anyone has installed them on their C7? Looks pretty simple to install, just a couple of screws. Any info on the product would be greatly appreciated.

Everything I've read about rear diffusers say they are worthless. If you like them, have at it. They do look good on some cars.

Diffuser mods are only "functional" if you consistently run speeds well over 150 mph, otherwise they're for looks only.

I put them on my car like the look is about it for sure. I do thing the car needs something more & that fits the bill for a small price. Plus a diff look than the next c7 parking next space to you..

But I got mine from a vendor in here & he put a paper lay out for you to be able to put down & drill holes in just correct place Robert

....or you can order the entire lower rear fascia in Carbon Fiber or Carbon Flash, which will include the diffuser fins.

Rear diffusers are not all show for some cars. GTRs have an aftermarket addon diffuser and rear plate commonly available that lowers the CD. I think the issue with ours is similar to their car that we would need an additional plate at the rear exhaust to complete the flat bottom and continue the smooth laminar flow out the rear for the diffuser to be effective. Just my .02
