Chevy Corvette C8 Stingray customers looking to add some go-faster flair to their sports car can do so with this new Corvette C8 Z06 / Z07 style wing from Sigala Designs.
According to Sigala Designs, the large rear wing included with the Z07 Package on offer for the new Corvette C8 Z06 will not fit the standard Stingray. However, Sigala’s replica wing was made specifically for those Stingray customers looking get the Z07 look for their mid-engine Vette.
The new Sigala Designs C8 Corvette Z06 / Z07 rear wing will fit both the Stingray Coupe and Stingray Hardtop Convertible models, and is offered with a plethora of options for the finish. These include carbon fiber, Carbon Flash, or the wing can be color-matched to Corvette paint finishes like Ceramic Matrix Gray, Elkhart Lake Blue, Long Beach Red, and Rapid Blue. The wing is also available unpainted for those customers that want something even more custom.
As for fitment, the new Sigala Designs wing can be mounted in the rear via two posts, or four posts. The spoiler uses the same inner holes as the standard Z51 High Wing, and offers the option to cover the outer holes for those that go with the two-post option. Sigala also says that customer vehicles without pre-drilled holes can use the provided template for easy mounting.
For those customers that may want to attempt the install on their own, Sigala also published a video detailing what it takes. The video is shot in a driveway, with the installer using rudimentary tools to get the job done. Looking over the video, it appears though the wing install requires that the rear bumper and the stock taillights are all removed.
Check out the full install video right here:
Pricing for the new Corvette C8 Z06 / Z07 style wing is set at $1,499.99, per the Sigala Designs website. Shipments will ramp up in September of 2022.

The 4-post option seems to be a much better solution…i.e., using the existing holes rather than covering them. I think the standard high wing looks better anyway, so this is not a change I would even want. In fact, I would not consider the Z07 package for the Z06 solely because of this wing design.
There are so many C8 customization options (which is great), but not the things that I think the C8 Stingray needs the most…Caravaggio was on the right track esp. with their redesigned hood, rear bumper and intakes.
I realize this article is just about the wing option, but would like to see a redesigned bumper cover that changes the hexagonal plate area for the Stingray and provides different tail light fitment options…without going overboard with a different extreme design…fitting some Ferrari F8-style tail lights would look fantastic (since the OEM units have to come out anyway), but I’ve always been a round tail light guy when it comes to Corvettes.
$110k just for the kit!!
PRETTY COOL!, and I definitely like the four post!
I have a 2021 Z51 with wing, with 4 mount points. I have removed the rear bumper twice, removed the wing, filled the holes
with the plastic panel connectors to give a smooth look and drove it around for a while . Easy to remove bumper, easy to remove wing.
Two post solution looks pretty cheesy. The four post looks a bit overdone, however, the real test will be can the fittings stand up to the force that will be applied to it at speed…
Douglas, we can certainly bracket those forces with some easy calculations. The real situation is more complicated due to the influence of the car to the flow, details of the angles, airfoil shape, interference from the struts etc. But we can make some estimates and those other factors will mostly reduce the real forces. Sorry, I am an old engineer so find imperial units more intuitive. To find an aero forces the general equation is:
L=q*S*Cl
Where q is dynamic pressure (what you feel holding your hand out the window) and for incompressible flow:
q=1/2 * ϱ * V^2 where ϱ is the density of the fluid, in this case, air.
Step 1, estimate the area, S. In this case, as a wing, area is the profile area, not the frontal area (like with bluff bodies like cars). I’d say about 6 feet long and a little under a foot in width, say 7 inches or 0.6 feet. (the back deck is very close to 5 feet wide, and the low spoiler is 4 inches wide for comparison)
S = 6×0.6 = 3.6 ft^2
Step 2, estimate the speed we plan as the design point. The stock Z51 is advertised to be capable of 185 mph. As we are dealing with imperial units we must be consistent, 185 mph = 271 feet/sec (60 mph = 88 fps)
Step 3, estimate the environment. Standard sea level air density is ~0.00238 slugs/feet^3 (a slug is an odd fallout as an imperial mass unit, one pound force applied to one slug accelerates at one foot/sec^2, so a slug weighs 32.17 pounds on Earth).
Step 4, estimate the “lift coefficient”. This is a constant that depends on the geometry, airfoil and the angle of attack or the angle with respect to the airflow. The best that can be done for small wings without flaps and slats (single element) is 0.8 to 1.2 or so. That thick sections with thick struts on the lifting side on the car will likely not even get there, so lets pick the CL=0.8.
So we have everything we need:
L = 1/2 * .00238 * 271^2 * 3.6 * 0.8 = 252 pounds.
We shouldn’t forget drag. Using the same methodology, and estimating the drag coefficient to be something about 0.2 (a guess, be my guest and look up some better numbers in Abbot and Von Doenhoff’s classic “Theory of Wing Sections”). So for drag:
D = 1/2 * .00238 * 271^2 * 3.6 * 0.2 = 63 pounds.
So the total as these two forces are 90º to each other the total is just the square root of the sum of the squares.
Force = (252^2 + 63^2)^(1/2) = 260 pounds.
Testing this would not be that tough, weights, ropes and pads, some pulleys and you can check for deflections and potential cracking.
Y’all have fun out there, if you have better numbers, please share!
LMAO these guys wash thier money but selling “premium” body kits which is nothing less than cheap fiber! Ernesto sigala had a failing company before and changed the name due to the bbb giving him a 1/5, and now he runs sigala designs, which funny enough has one “remote” location in tj where they only work on high end cars of tj, suburbans, escalades, armored f250s. Could be a money wash but i will say that for the little time ive know ernesto, the man is literal scum!
