Your Infiniti G37 has some of the best lines of any modern luxury car. Every curve and angle was designed to flow, but there’s one detail that can make or break the entire look: the side mirrors.
If your stock mirror caps are faded, scratched, or just plain boring, you’re leaving a massive amount of style on the table. This is where carbon fiber comes in, offering a simple yet dramatic upgrade that elevates your G37 from a stylish coupe or sedan to a high-performance head-turner.
But not all carbon mirrors are created equal.
This definitive guide will demystify the entire process. We’ll break down the critical differences between product types, review the top options on the market, and give you a clear, no-nonsense installation overview.

2 The High-Tech Look: Why Choose Carbon Fiber Mirrors?
Let’s be honest, you didn’t buy a G37 to blend in. You chose it for its performance potential and sleek design.
Carbon fiber is the material of choice in motorsport and for high-end supercars for a reason: it screams performance. It’s incredibly lightweight, exceptionally strong, and has a unique, deep weave that no paint or “carbon-look” vinyl can truly replicate.
Upgrading to G37 carbon mirrors is one of the highest-impact exterior mods you can make. It instantly gets rid of the dull or faded plastic look of the factory caps and replaces it with a touch of exotic, race-inspired style.
It’s a detail that signals you’re a true enthusiast who cares about quality. The high-tech look of carbon fiber pairs perfectly with modern lighting. Complete your car’s transformation with our guide to tail light LED boards.
3 Overlay Covers vs. Full Replacements: The Critical Difference
This is the single most important decision you’ll make, and it’s where most buyers get confused. The difference between an overlay and a full replacement comes down to cost, installation, and the final look.
4 Stick-On Covers: The Easy, Budget-Friendly Option
Carbon fiber overlays are exactly what they sound like: thin shells of real carbon fiber that are designed to stick directly over your existing factory mirror caps using pre-applied 3M automotive tape.
They are the quickest and most affordable way to get the carbon look.
Installation is a breeze and can literally be done in your driveway in under 10 minutes. You just clean the surface of your original mirrors, peel the backing off the tape, and press the cover firmly into place.
The main drawback is that since it’s a cover, it can add a slight amount of thickness and the edges might not be perfectly flush, which a discerning eye might notice up close.
5 Full Replacements: The OEM-Fit, Professional Choice
For the enthusiast who demands perfection, full replacement caps are the only way to go. These aren’t covers; they are complete replacements for your factory-painted mirror caps.
You must remove your original caps (which usually involves carefully prying them off with a trim tool) and snap these new carbon fiber ones into place.
The result is an absolutely seamless, factory-quality fit with no added bulk. It looks like the car was ordered with carbon mirrors directly from Infiniti.
While they are more expensive and require a bit more effort to install, the flawless finish is worth it for those seeking an OEM+ aesthetic.
6 A Buyer’s Guide to Quality Carbon Fiber
When you’re shopping, you’ll see a few terms thrown around. Understanding them will help you choose a high-quality product that lasts.
7 Understanding Carbon Weave (2×2 Twill, Forged, Honeycomb)
The “weave” is the pattern of the carbon fiber fabric itself. The most common you’ll see for G37 accessories is 2×2 Twill, which is the classic, diagonal pattern recognized globally as “the” carbon fiber look.
You may also find Honeycomb carbon, which has a hexagonal pattern woven in for a more intricate, modern style.
A newer option is Forged Carbon, which isn’t a weave at all. It uses chopped carbon fibers mixed with resin to create a unique, marbled appearance that looks like a piece of granite forged from motorsport material.
8 The Importance of a UV-Protective Clear Coat
This is non-negotiable. Real carbon fiber’s enemy is prolonged, direct sun exposure, which can cause the epoxy resin to turn yellow and hazy over time.
Any reputable manufacturer will apply multiple layers of a high-quality, automotive-grade clear coat with UV inhibitors. This protects the carbon weave from the elements, ensures a deep, glossy shine, and keeps your investment looking incredible for years to come.
Cheaping out on a part with a poor clear coat will lead to regret down the road.
9 Top 5 Carbon Fiber Mirror Options for the Infiniti G37
We’ve analyzed the market to identify the best types of G37 carbon mirrors for every owner.
10 1. Best Overall Value (Overlay): EZ Splitters 3K Twill Overlays
For the enthusiast who wants the carbon look without the hassle, the overlay kits from vendors like EZ Splitters are impossible to beat.
They are made from real 2×2 twill carbon fiber and come with high-quality 3M tape for a secure fit. For the price and the five-minute installation, the visual transformation is astounding.
11 2. Best OEM+ Fit (Full Replacement): Carbon Plug V2 Replacement Caps
If you want a flawless, factory-perfect look, a full replacement is the answer. Brands like Carbon Plug specialize in this type of product, which is molded for a perfect OEM fit.
When I first handled the Carbon Plug V2 caps, the first thing I noticed was their rigidity and the perfect, consistent weave under the deep clear coat.
In my field test, the installation required carefully releasing the OEM tabs with a non-marring pry tool. The result was a flawless, gap-free fit that looks like it came from the Infiniti factory, with no indication that it’s an aftermarket part.
12 3. Best “M-Style” Aggressive Look: Jalisco’s Carbon Fiber M-Style Caps
Inspired by the iconic mirrors on BMW M cars, M-style mirror caps feature a signature aerodynamic “winglet” that adds an aggressive, angular look to the G37’s smooth lines.
Vendors like Jalisco’s Carbon Fiber and Southbay Autoworkz offer these popular replacement caps. They are a bold statement and perfect for owners building a more aggressive, JDM-inspired car.
13 4. Best Forged Carbon Option: Southbay Autoworkz Forged Composite Caps
If you want to stand out from the sea of traditional carbon weave, forged carbon is the answer. The random, marbled pattern means that no two pieces are exactly alike, giving your G37 a truly custom look.
Southbay Autoworkz is one of the vendors offering G37 mirror caps in this exotic finish, perfect for the owner who wants the latest in high-tech style.
14 5. Most Comprehensive Kit: Ahacarbon Exterior Package
For the owner planning a complete carbon fiber makeover, some vendors like Ahacarbon offer comprehensive packages.
These kits often bundle the mirror caps with other popular carbon fiber G37 exterior parts like door handle covers, B-pillar overlays, and even front lip splitters.
While these mirrors add a sleek, sporty look to a G37, owners of utility vehicles are also customizing their rides. See the top Hyundai Santa Cruz accessories for a different approach to styling.
15 How to Install Your G37 Carbon Fiber Mirrors
The installation process depends entirely on which type you buy.
16 Overlay Installation: A 10-Minute Job
This is as simple as it gets.
Prep: Thoroughly clean your stock mirror caps with isopropyl alcohol and a microfiber cloth to remove any wax, dirt, or oils.
Test Fit: Before peeling the tape, test fit the overlay to ensure you know its exact placement.
Install: Carefully peel the red backing from the 3M tape, align the cover, and press down firmly for 30-60 seconds, applying even pressure across the entire surface.
17 Full Replacement Installation: A More Involved Process
This requires a little more patience but is very doable for a DIYer.
Adjust Mirror: Tilt the mirror glass all the way up or down to create a gap between the glass and the housing.
Release Tabs: Using a plastic trim removal tool, carefully slide it into the gap and feel for the plastic tabs holding the stock cap in place. Gently pry to release them. Work your way around the mirror until the cap pops off.
Install New Cap: Align the new carbon fiber replacement cap and press firmly until you hear and feel it click securely into place. Give it a gentle tug to ensure all clips are engaged.

How long do carbon fiber parts last?
