The bottom panel that bridges the exhaust opening seems a bit narrow. Not sure my exhaust would fit that opening. Stylistically it looks good, but it may be kind of narrow functionally. Would you have an option to simply extend straight across?

There can definitely be more changes made to the diffuser as the final prototype is yet to be fully developed. We'll make sure to share these notes with our development team.
Sorry again for the wait everyone, we are trying to finish out this project as soon as possible. We'll post updates as soon as more info is available.

Thanks again!

Yeah, I didn't think about how narrow it is and which exhaust tips could work with it Haha but I didn't think about it because my exhaust dumps right behind the rear tires

clinthart2003

idea for you.... take that bottom panel and flip it. have it extend down rather than up into the port area. As long as that ******* thing isn't making lift LOL!!!!! we need downforce, not lift. So, angle it up like a wing from the inside of the car upwards to the exit. :-)

PS. Hurry the hell up and build me one!

I like the updated version but have the same concern as many... Will my current tips for that slot? Also agree with the fact functionality needs to be seriously considered and tested. A purely cosmetic piece is garbage in the end. It definitely needs to extend forward to reduce the air entering the rear valance.

It looks pretty, and calling it a race version is probably a misnomer.
It's unlikely any useful downforce will result from that design.

Thanks again for the feedback everyone, we are taking notes!

Any updates on this?

Right? F it. i have the splitter and side skirts... might as well complete the set haha

C7 Carbon

Thanks for the follow up, our team is still working on the prototype unit, but we'll make sure to post some pics of it installed on the C5 as soon as possible. Thanks again!

Hey there, thanks for giving us some more modern options for body and aero panels for the C5.

If my input helps at all, here it is.

First of all, as mentioned, it has GOT to be functional. Whatever design compromises you have to make to do that than do it.

Second, if it can be designed to actually produce down force, than even better. Spoilers don't look very good on C5s so if there's a way to make a complete EFFECTIVE aero package with a big wickerbill and diffuser than that's what modern C5 guys want.

Make it as aggressive as necessary. We've already got half *** cosmetic diffusers. The rest of us want functional.

Finally, where you're allowed to make decisions based purely on aesthetics, in my opinion make it modern and Racey looking. Same as I said above, we already have curvy and fat edged diffusers that "match" the C5 factory styling. Do something with sharp edges and exposed bolts. Proportion the angles and shapes to the car of course, but make it modern looking. Your second render was much better than the first.

Also.... Make a version out of plastic or fiberglass for poor people like me haha. I mean I'll spring for a carbon one if I have to but it won't be for a while, and I'm not going to use it in a race series where every ounce of weight matters. Most of these will probably be put on street cars.

C7 Carbon

Thanks again for your input, we appreciate it very much!

the chances of making this fully functional AND at a pricepoint that people will pay for street cars is pretty low.

if it looks as good or better than the carbon creation stealth one thats out. not heavy and added on but actually looks like it flows with the car. I'll be interested. CC's are months out since they changed their supplier. i was all about grabbing one but he can't fill any orders.

If it's all ricey and angular. i don't care how functional it is. it won't be for me.

I agree with this statement. I made the original Stealth diffuser for the other vendor. You will find that there are so many opinions and taste that you can not please eveyone. I liked the 2nd rendering. To me it needs to have smooth transitions to flow with the lines of the C5. No sharp angles or lines. I'm not a weekend racer so I would not put something on my car that screams track gear. I feel the majority of people that purchase from you or most of the other vendors are mostly wanting pieces for looks. I did alot of research before making my rear diffuser and found that none of the diffusers offered by vendors had any hard r&d data or testing to show benifits of their product. To get a full track race diffuser you basicslly need to have a race fab shop make one. Just my opinion. This item is a hard sell either way you go.

db2xpert

IMO, while the design is looking better, the overall title says RACE edition.
If you want something that just looks nice, this will probably get there.
Unfortunately, is not in the same galaxy as a RACE diffuser.... that would interest me.

JuicedH22

THIS x100000 There is absolutely a market in the c5 racing world for a FUNCTIONAL diffuser (and several members on here can help with what makes a diffuser functional). That same market that will purchase a functional diffuser, will NOT buy a 'just for looks' show piece that is for those just going for a 'look'. While the market size is different there, I would also argue the price a racer is willing to pay for something that works is also higher; as there is NOTHING on the market. Everything is custom fabricated.

This thread has been running since Oct 30 of last year -- so a basically a full year.
There are enough pics of real racing diffusers, and easily obtained by looking at the C5R and C6R racecars.

Unfortunately we have not seen anything from the vendor that even begins to be functional as a "RACE" diffuser.
People have provided good pics of serious diffusers.
All serious input has seemingly been ignored.

We're probably all just wasting time on this topic as part of this thread.

2k2wranglerx

it took about a year for them to do the front one.

I hold out hope.

STALION

Has to appeal to both functional use, as well as look good for the masses, or else it wouldn't be worth their time to make.
