The Porsche 911 Stinger GTR is a carbon-fiber body kit from TopCar Design, not a factory Porsche. It fits the 991 Turbo and Turbo S and replaces about 90 percent of the exterior with 24 carbon panels. Photos on this page show stock 991 Turbo donor cars, not Stinger GTR conversions.
In this article, we’ll explain the 911 Stinger GTR, TopCar’s wide carbon take on the 991 Turbo. We’ll cover what the kit changes, what it costs, and what to check before buying.

What the Stinger GTR Is
The Stinger GTR is a body kit made by TopCar Design, a tuning company founded in 2004. Today it builds kits for Porsche, Lamborghini, McLaren, and Mercedes-Benz. It is not a factory Porsche model. You start with a normal 991 Turbo or Turbo S, and TopCar makes it look much wider and more aggressive.
TopCar calls it the most complex project it had ever done, and it took nine months to develop. The result looks closer to a race car than a road car, with big intakes, flared fenders, and a large rear wing.
This is a stock 991 Turbo S, the car TopCar starts with.
If you want other takes on a modified 911, our RWB Porsche guide and Singer Porsche guide show two very different approaches.
The 991 Turbo Underneath
Under the carbon, it’s still a 991 Turbo, which is no bad thing. The 2013 Turbo S made 560 PS and 700 Nm from its 3.8-liter twin-turbo flat-six. It hit 100 km/h in 3.1 seconds and topped out at 318 km/h.
This stock 991 Turbo S shows the car before any conversion.
The 2016 update raised the Turbo S to 580 hp and the Turbo to 540 hp. Either car makes a strong base. For the full story of the factory car, see our Porsche 911 guide.
The Carbon Body Kit
The kit has 24 carbon-fiber panels, and it changes about 90 percent of the outside of the car. You get new front and rear bumpers, wider front and rear fenders, door pads, side skirts, a hood, a front splitter, a rear diffuser, and a rear wing.
This is a stock 991.2 Turbo S, and the kit replaces most of these rear panels.
Some parts come in clear-coated exposed carbon, so you can see the weave. Others come primed, ready to paint in the car’s color. The hood, diffuser, splitter, and rear wing are listed in exposed carbon.
The gen.2 kit
TopCar later released a Stinger GTR gen.2 kit for the 991 Turbo and Turbo S. It lists at €37,500 and adds GT3 RS-style vents on the front fenders and a new rear wing. With extra engine work, TopCar offers to take the gen.2 car to 750 hp. Ask a seller which generation of kit their car has.
How It Gets Fitted
This is not a bolt-on kit. Several of the carbon panels are bonded straight to the steel body, so the work is close to permanent.

TopCar fits the kit at its own workshop, or sends its team to the owner by special request. The shop can only finish about two cars a month.
The Optional Power Kit
The body kit doesn’t add power on its own. For the original kit, TopCar offered a separate power upgrade that added 60 hp and 130 Nm of torque.

Not every car got it, so don’t assume a Stinger GTR has the extra power. Ask for the invoice and a dyno sheet. Wheels were also offered through ADV.1, TopCar’s wheel partner.
What It Costs
TopCar lists the original body kit at €34,080. Fitting adds €6,500 and paint adds another €6,000. That puts a finished original kit at about €46,580. Shipping, taxes, wheels, and the power kit cost extra, and that’s on top of the 911 Turbo itself.
| Item (original kit) | TopCar list price |
|---|---|
| Body kit with carbon parts | €34,080 |
| Fitting and removal of stock parts | €6,500 |
| Paint | €6,000 |
| Gen.2 body kit, for comparison | €37,500 |
| Original kit total before extras | About €46,580 |
Buying One
Start with the Porsche
Check the base car first. Run the VIN, get the factory build sheet, and confirm whether it started life as a Turbo or a Turbo S. Then check service history, recalls, and any accident damage. Our 911 buyer’s guide covers the basics.

Then check the kit
Ask for TopCar’s invoice and photos of the build. Look closely at panel gaps, bonded edges, and any cracks in the carbon. A body shop that knows composites is worth paying for.
Finally, tell your insurer exactly what’s been changed. Confirm the car is covered at the right value before you buy.
