C8 Corvette widebody kits compared
This page started as a post about one car, the Label Motorsports widebody C8 from the 2021 SEMA Show. It now covers every C8 widebody kit and build I could verify, with the maker, what comes in the box, how much width it adds, and what the maker or a named source says it costs. Where a number was never published, the table says so.
| Kit | In the kit | Material | Added width | Published price |
|---|---|---|---|---|
| Pandem (Rocket Bunny) | Front lip, side skirts, front and rear over-fenders, rear wing | FRP | +40 mm front +70 mm rear |
$8,000 |
| Liberty Walk | Front bumper with splitter, side diffusers, rear bumper, rear wing, front and rear flares | Standard or carbon fiber reinforced | Not published | $19,580 $21,780 carbon |
| Sigala Designs C8RR | 32 pieces: every body panel except the doors, plus hood, roof and wing | Fiberglass and carbon mix, or full carbon | 6 in | From $14,995 $24,995 carbon |
| Duraflex Grand Veloce | Front and rear fender panels, sold separately | Fiberglass | Up to 4 in | $1,709 front $1,709 rear |
| Streethunter Designs | Wider fenders, rear quarter panels, rear diffuser, wing, nose pieces | Carbon wing, diffuser and splitter | Not published | Not confirmed |
| Label Motorsports Vouno | 29 carbon pieces on the SEMA car, built as a complete car | Forged carbon fiber | Not published | Not published |
Prices are parts only, in U.S. dollars, as last published: Pandem from GReddy’s U.S. listing in October 2026, Liberty Walk from January 2023, Sigala from July 2021, Duraflex from March 2022. Check the maker before you budget.
Read those prices as the first line of the bill. GReddy’s listing says the Pandem parts ship in raw gel coat that needs prep before paint, and truck freight is extra. Paint, bodywork, installation, wheels and tires come on top of every kit here.
Factory wide body vs aftermarket widebody: not the same thing
Chevrolet sells its own wide body. The Z06, Grand Sport and ZR1 are 79.7 inches (2,024 mm) wide. The Stingray is 76.1 inches (1,933 mm). That is 3.6 inches of extra width, and it comes with tires to fill it: 275/30ZR20 front and 345/25ZR21 rear, against 245/35ZR19 and 305/30ZR20 on the Stingray.
An aftermarket widebody kit is a different job. It adds flares or replacement panels to a narrow-body car. The suspension, the hubs and the stock wheels stay where Chevrolet put them, so the extra body width is empty until you change wheels and tires. Some kits also need the factory fenders cut, which you cannot undo.
The money is worth a look too. For 2027 the Grand Sport puts the factory wide body on the Stingray’s 535 hp LS6 for $15,000 more than a Stingray at the same trim. A Liberty Walk kit at $19,580 and a full carbon Sigala kit at $24,995 both cost more than that at their last published prices, before paint. I ran the full numbers in Grand Sport vs Stingray.
I have owned four C8s: a Stingray, two Z06s and the ZR1 I have now, so I have owned both the narrow body and Chevrolet’s wide body. If width is all you want, I would buy the factory wide body. The kits make sense when you want a shape Chevrolet does not sell, and you accept that the car becomes a project.
Every C8 widebody kit, one by one
Pandem (Rocket Bunny) C8 Aero
Pandem announced its C8 kit in 2020, and the first customer car, a black Stingray on air suspension, was shown that November. GReddy sells it in the U.S. for 2020 and newer C8 coupes. The complete kit is $8,000 in FRP: a front lip ($1,250), side skirts ($1,450), front over-fenders ($2,100), rear over-fenders ($2,100) and a rear wing ($1,450). Bought one at a time the parts total $8,350.
The over-fenders are listed as +40 mm front and +70 mm rear, about 1.6 and 2.8 inches. The listing does not say whether that is per side. It does say body cutting and inner fender sealing are required. It is also the kit on TheStradman’s C8 Stingray.
Liberty Walk
Liberty Walk released its C8 Stingray kit in January 2023. Per GM Authority’s report, the complete kit is a front bumper with an integrated splitter, side diffusers, a rear bumper, a rear wing and front and rear fender flares. It was priced at $19,580, or $21,780 in carbon fiber reinforced form. The wing alone was $4,400, or $6,600 in carbon. Unlike the Pandem parts list, it includes both bumpers. No width figure was published.
Sigala Designs C8RR
The C8RR is the most complete kit of the group. CorvetteBlogger covered the finished kit in July 2021: 32 pieces that replace every body panel except the doors, including a vented hood, widebody fenders and quarter panels, a rear diffuser built around a center quad exhaust, a roof and a three-piece high wing. It makes the car six inches (152 mm) wider. Pricing started at $14,995 in a fiberglass and carbon mix and $24,995 in full carbon. Parts were also sold singly, such as the hood at $1,970 and the high wing at $1,195.
Duraflex Grand Veloce
This is the cheapest way in. Duraflex, out of Fullerton, California, makes the Grand Veloce flares in hand-laid fiberglass with a riveted-on look. CorvetteBlogger listed them in March 2022 at $1,709 for the front panels and $1,709 for the rear, $3,418 for both ends, adding up to four inches (102 mm) of width. The car in that feature ran ADV.1 wheels in 20×9.5 front and 21×12 rear on air suspension, which tells you how much wheel it takes to fill the flares.
Streethunter Designs
TJ Hunt’s kit was designed by Jon Sibal with a GT3 race car look, and it was first shown as a rendering in February 2020. The design covers wider fenders, rear quarter panels, a rear diffuser, a race wing and nose pieces. TJ Hunt’s own car, a Torch Red Stingray, was finished in August 2021 with a carbon fiber wing, diffuser and front splitter. I could not confirm a current price or a width figure, so the table leaves both open.
Label Motorsports Vouno: the SEMA 2021 build
Label Motorsports is a shop in Ada, Michigan, owned by Andy Siradakis. Its widebody C8 program is called Vouno, from the Greek word for mountain. Label showed the first renderings in August 2020. The finished car took 17 months and was revealed at the 2021 SEMA Show in Las Vegas, in the Gentex Corporation booth. It was shown again at the 2022 Michigan International Auto Show in Grand Rapids.
What makes it different from every kit above is that you do not buy it in a box. Label builds the whole car. From the Vette Vues interview with Siradakis and Label’s own build pages, the SEMA car carried:
- 29 carbon fiber pieces, finished in forged carbon: hand-cut chips laid over a woven carbon base.
- Air struts that Label engineered for the car.
- CEIKA big brakes with an integrated e-brake.
- Brixton Forged wheels.
- An all-titanium exhaust and a functional aero hood.
- Clear taillights developed with Gentex, plus Alcantara interior trim.
Label has kept going since. Chassis number 3 was its first widebody C8 convertible, a 35-piece program with full carbon fiber replacement fenders and Brixton AS01 wheels, built for a client in Texas as one of an initial five builds. The Label pages I read give no price and no width figure. You commission a car through Label Motorsports directly.
Video: the Label Motorsports widebody C8 in 4K
Khoality Media filmed the Label car in 4K and published it as “One of a Kind Widebody C8 Built by Label.” This is the video the first version of this post was written around.
The widebody C8s at SEMA 2021
SEMA 2021 had widebody C8s all over the floor. Vette Vues walked the Las Vegas Convention Center and logged these:
- Competition Carbon: three cars, in the Extreme Dimensions booth, an air suspension company’s booth, and the Toyo Tires walkway between the Central and South Halls.
- Streethunter Designs: the Jon Sibal design from TJ Hunt.
- Sigala Designs: the C8RR, with one car entered in SEMA’s Battle of the Builders.
- Label Motorsports: the Vouno, in the Gentex booth.
- Rocket Bunny: the Pandem kit.
What a widebody kit does to wheels, tires and ride height
The kit is the cheap part of the decision. Three things follow it.
- Wheels and tires. A Stingray leaves the factory on 245/35ZR19 front and 305/30ZR20 rear tires. Put flares over that and the wheels sit inside the new fender line. Filling it takes wider, lower-offset wheels or spacers, and tires to match. GReddy lists wheel and tire specs for the Pandem kit as TBA, so fitment is on you and your wheel shop. Start with the stock C8 wheel sizes.
- Ride height. The Label car, the Duraflex feature car and the first Pandem car all sit on air suspension. The look depends on getting the car low, and the extended splitters on these kits sit close to the road.
- Cutting. Over-fender kits like Pandem need the body cut. Decide that before you order, not when the car is on the lift.
Two things from my own cars. Lowering my Z06 put the front lift out of its working range, so do not count on the factory lift to save a low splitter. And I broke a rear half shaft launching my Stingray. A much wider rear tire means more grip at launch on the same half shafts.
Frequently asked questions
What is the Label Motorsports widebody C8 Corvette?
It is a widebody C8 program called Vouno from Label Motorsports in Ada, Michigan. The first car took 17 months and was revealed at SEMA 2021 in the Gentex booth with 29 forged carbon fiber pieces, air struts, CEIKA brakes and Brixton Forged wheels. Label builds complete cars for clients instead of selling a boxed kit.
How much does a C8 Corvette widebody kit cost?
Published parts prices run from $1,709 per end for Duraflex fiberglass flares to $8,000 for the Pandem kit, $19,580 to $21,780 for Liberty Walk, and $14,995 to $24,995 for the Sigala Designs C8RR. Paint, bodywork, installation, wheels and tires are extra on every one of them.
How much wider is a widebody C8 Corvette?
Chevrolet’s factory wide body is 79.7 inches across, 3.6 inches wider than the 76.1 inch Stingray. Aftermarket kits vary. Sigala’s C8RR adds six inches, Duraflex’s Grand Veloce adds up to four, and Pandem’s over-fenders are listed at 40 mm front and 70 mm rear.
Do you have to cut the body to fit a C8 widebody kit?
For the Pandem kit, yes. The U.S. listing says body cutting and inner fender sealing are required. Sigala’s C8RR is described as replacing every body panel except the doors. Ask each maker what has to be cut before you order, because a cut fender cannot be put back.
Which C8 Corvettes come with a factory wide body?
The Z06, Grand Sport and ZR1 all use Chevrolet’s 79.7 inch wide body, against 76.1 inches for the Stingray. For 2027 the Grand Sport pairs that body with the Stingray’s 535 hp LS6 engine for $15,000 more than a Stingray at the same trim level.
What are the best-known widebody C8 Corvette builds?
Three of the best documented are Label Motorsports’ forged carbon Vouno from SEMA 2021, TJ Hunt’s Torch Red Stingray with the Streethunter Designs kit, and TheStradman’s Stingray with the Pandem kit. Competition Carbon also brought three widebody C8s to that same SEMA show.
