If you've ever looked at your Infiniti and wished it had a bit more of that Godzilla DNA, then a g37 coupe gtr body kit is probably the first thing on your wishlist. It's one of those modifications that completely changes the identity of the car. The G37 is already a handsome machine with its smooth lines and sporty silhouette, but let's be honest—it's a bit "soft" compared to its big brother, the R35 GT-R. By adding a kit inspired by the GT-R, you're essentially bridging the gap between a luxury grand tourer and a legendary street monster.
The G37, specifically the V36 platform, actually shares a lot of its underpinnings with the GT-R anyway. They're cousins in the Nissan family, so it's not like you're trying to put a Ferrari body on a Honda Civic. There's a certain logic to it. When you get the proportions right, a G37 with a GT-R style front end looks like something that could have rolled straight out of the factory as a high-performance variant.
Why go for the GTR look anyway?
The main reason people go this route is presence. The stock G37 front bumper is fine, but it's a little understated. It's got that "entry-level executive" vibe. On the other hand, the GT-R is all about aggression. It has those massive cooling ducts, a sharp nose, and that unmistakable rectangular grille. Putting a g37 coupe gtr body kit on your ride gives it an instant attitude adjustment.
It's also about standing out in a crowded car scene. There are a million G37s out there with the standard IPL (Infiniti Performance Line) bumpers or simple lip kits. Don't get me wrong, the IPL look is clean, but it doesn't have the same "get out of my way" energy that a GT-R face does. If you're the kind of person who likes to take their car to meets or just wants to turn heads at every stoplight, this is one of the most effective ways to do it without spending six figures on an actual R35.
Breaking down the main components of the kit
Usually, when we talk about these kits, we're looking at a few specific pieces that do the heavy lifting. You can't just change the bumper and call it a day—well, you can, but it might look a little unfinished if you don't consider the rest of the car's lines.
That iconic front bumper swap
The front bumper is the star of the show. Most g37 coupe gtr body kit options focus heavily on replicating that R35 "mouth." You'll notice the vertical air intakes on the sides, which often house LED daytime running lights. These aren't just for show; they provide a much-needed visual width to the front of the G37. One thing to keep in mind is that the G37 is narrower than a GT-R, so a good kit has to be designed to taper correctly into the G37's fenders. If the transition is clunky, the car will look "off" from the side profile.
Vented fenders and wider arches
To really sell the look, a lot of enthusiasts opt for vented front fenders. The GT-R has those functional side vents right behind the front wheels, and adding similar fenders to the G37 helps tie the front bumper into the rest of the body. It adds a layer of complexity to the side of the car that the smooth factory panels just don't have. Some kits even go full widebody, which means you're looking at rear over-fenders as well. That's a much bigger commitment, but man, the stance you get with a widebody G37 is hard to beat.
Side skirts and rear diffusers
You can't have an aggressive front end and then leave the stock, flat side skirts. It makes the car look like it's tilting forward. Most kits include side skirts that sit a bit lower and have a more angular design. As for the rear, a GT-R style diffuser is the cherry on top. The GT-R is famous for its massive quad exhaust tips and that functional-looking rear aero. A good diffuser will wrap around your existing exhaust and give the back of the G37 that "planted" look.
Fitment and the reality of the installation process
Here's the part where I have to be a bit of a realist. Installing a g37 coupe gtr body kit isn't always a "bolt-on and go" type of deal. If you're buying a cheaper fiberglass kit from a random site, you're going to have your work cut out for you. Fiberglass often needs a lot of sanding, trimming, and even a bit of heat to sit flush against the metal panels of the car.
I've seen plenty of DIY projects where the owner thought they could just slap the bumper on and call it a day, only to realize there's a half-inch gap under the headlights. That's not a look you want. Unless you're a pro with body filler and a sander, you're probably going to want to take the kit to a reputable body shop. They'll do what's called a "test fit" first, make all the necessary adjustments, and then prep it for paint.
Also, don't forget about the underside. Sometimes these aftermarket bumpers don't line up perfectly with the factory splash shields. You might need to get creative with some custom brackets or zip-tie stitching (the "drift stitch" look is a vibe, but maybe not on a clean G37 build).
Material choices: Fiberglass versus Polyurethane
This is a big debate in the G37 community. Most of the g37 coupe gtr body kit options you'll find are made of FRP (Fiberglass Reinforced Plastic). FRP is great because it's lightweight and holds its shape really well, which allows for those sharp, crisp lines that define the GT-R look. The downside? It's brittle. If you're driving a lowered car and you hit a speed bump too hard or scrape on a steep driveway, fiberglass is likely to crack.
Polyurethane is the other option, though it's harder to find for full GT-R style conversions. Poly is much more flexible. You can practically bend a poly bumper in half and it'll pop back into shape. It's way better for daily driving. However, because it's so flexible, it's harder to get those razor-sharp edges, and it can sometimes sag over time if it's exposed to extreme heat. For most people doing a show-style build, FRP is the standard, just be prepared to drive carefully.
The visual impact and street presence
Once the kit is on, the paint is matched, and the car is back on the road, the transformation is pretty wild. A G37 with a GTR kit doesn't just look like a modified Infiniti; it looks like a whole different car. To really finish the look, you're going to need the right wheels and suspension setup.
If you put a massive, aggressive body kit on a car that's still sitting at stock height on 18-inch factory wheels, it's going to look goofy. You need some concave wheels with a bit of "poke" to fill out those new lines. Dropping the car an inch or two on coilovers or bags is basically mandatory. When everything works together—the aggressive front fascia, the wider-looking fenders, and a nice set of deep-dish wheels—the G37 finally looks as fast as it feels.
Final thoughts on the G37-R transformation
At the end of the day, installing a g37 coupe gtr body kit is about personal expression. There will always be purists who say, "just buy a GT-R," but those people are missing the point. Not everyone has $80,000 to drop on a supercar, but many of us have a G37 and a vision.
The G37 is a fantastic platform. It's got a great V6, a solid RWD (or AWD) layout, and a huge aftermarket. Giving it the GT-R aesthetic is just a way of leaning into that Nissan heritage. It's a project that requires patience, especially when it comes to fitment and paint, but the result is a car that feels special every time you walk up to it in a parking lot. It's not just a commute anymore; it's a statement. So, if you're on the fence, just make sure you do your research on the kit quality, find a painter you trust, and get ready for a lot of people asking you "Wait, is that a Skyline?"
