Anyone have this rear diffuser on their C8?

Any impressions would be appreciated.

Seen it in person installed at Paragon and it is pretty nice! They also have data that it actually gives you nice downforce numbers compared to other vanity diffusers being sold. I'll be installing one once the next batch gets shipped

Looks really nice and aggressive but I'm thinking it might be a scrape issue. The car is already low and the last thing I need is something to catch it and pull it and everything else out along with it.

Downforce
I thought diffusers were used to 'diffuse' the pressure underneath a car as it comes out the back? I didn't know they played a hand in downforce as well.

Their claims are drag "reduction", but the chart at Paragon Perf actually shows a drag "increase" with speed.
To be honest, I am a little skeptical with all these charts I see from vendors where they show a stock performance chart, and the part they are selling shows a NEAR LINEAR and completely proportional increase in performance. Look! 17HP gains! But in fluid dynamics and complex systems, things rarely make linear changes like that. There are going to be odd resonances and things that are hard to predict that you will see in legit performance data.
When I see those types of charts, it screams "snake oil" to me. That said, the diffuser looks nice. If it is a single part and bolts on easy, looks like a much easier install than some of the others I have seen. Also seems to have LESS of a problem with ground clearance. Some of the others are ridiculously low.

Thanks for the clarification. Because of my lack of knowledge I've done a bit more research on diffusers for personal knowledge.
I just wanted to post and say and say I stand corrected and thanks!
