Fly1Motorsport G37 coupe carbon fiber fenders

Infiniti G37 Carbon Fiber Fenders for Sale. Wide Body Aftermarket Fenders for G37 Coupe.

The Infiniti G37 carbon fiber fenders are one of the most impactful exterior upgrades available for the G37 coupe platform. If you are building a dedicated track car, a time attack build, a show car, or a street machine that needs aggressive fitment and reduced weight over the front axle, a quality set of carbon fiber fenders for G37 coupe applications gives you the widened stance, the weight reduction, and the visual presence that factory fenders cannot deliver. At McClain Auto Part, we source and supply aftermarket exterior components for performance builds out of Cleveland, Ohio. The G37 aftermarket fenders we carry include verified fitment units from established suppliers in the carbon fiber body panel market.

G37 coupe builders come to us for a few reasons. Some are running a widened front track on a dedicated track car and need fenders that clear the additional wheel and tire fitment without cutting into factory metal. Others are building a show or street car where the widened front fender stance is a specific aesthetic goal. In addition, a group of time attack and autocross builders specifically looks for Fly1Motorsport G37 fenders and similar quality aftermarket carbon fiber options because the weight reduction over the front axle contributes meaningfully to overall chassis balance on a car that is already front-heavy from the factory.

Whatever the build is, the goal is the same. A clean, well-fitted set of Infiniti G37 wide fenders that installs correctly and complements the rest of the build.

Why Carbon Fiber Fenders for the G37

The G37 coupe is a well-balanced performance platform from the factory. However, the VQ37 engine sitting ahead of the front axle creates a front-heavy weight distribution that most G37 performance builders address through suspension tuning, ballast placement, and component weight reduction. Replacing the factory steel front fenders with carbon fiber units is one of the more practical weight reduction steps available for the front of the car.

Weight Reduction Numbers

Factory G37 coupe steel fenders weigh significantly more than a comparable carbon fiber replacement. A quality carbon fiber fender for the G37 typically weighs between 3 and 5 pounds per side depending on layup specification and construction method. The factory steel equivalent runs significantly heavier. As a result, a pair of carbon fiber fenders removes meaningful unsprung and front-end weight from a location where reduction has a direct positive effect on chassis balance, steering response, and front grip under braking.

Wide Fender Fitment

The Infiniti G37 wide fenders configuration provides additional clearance over the factory fender line. This matters for builders running wider wheel and tire combinations, aggressive camber settings, or coilover suspension setups that change the wheel position relative to the factory fender arch. Specifically, a widened fender allows fitment of wheels and tires that would otherwise contact or visually protrude beyond a factory fender line without requiring permanent modification to the body structure.

Fly1Motorsport Construction Quality

Fly1Motorsport G37 fenders are among the most recognized aftermarket carbon fiber fenders in the G37 community. Fly1 produces carbon fiber body panels using a mold derived from the factory fender geometry, which means mounting point locations and body line alignment follow the factory reference closely. The result is a carbon fiber fender that installs with factory-style mounting hardware and aligns to adjacent body panels without the fitment gaps and inconsistencies common in lower quality carbon fiber body panel options.

Technical Details

Confirm your specific model year and build configuration before ordering. Call us with your application and we confirm the correct fitment for your car.

What Is Included

Here is what a typical G37 carbon fiber fenders package from McClain includes.

Standard With Most Units

• Driver and passenger side carbon fiber fender pair
• Mounting hardware where included with the specific unit
• Gel coat finish on exterior surface

Available on Select Units or by Request

• Fender liner, confirm compatibility with your specific build
• Vented fender configuration
• Raw carbon fiber finish without gel coat on select units

A Note on Finish

Most units ship with a gel coat finish on the exterior surface. This provides a paintable surface that accepts automotive primer and paint directly. If you want an exposed carbon weave finish, confirm raw carbon options at time of order. Raw carbon fiber fenders require clear coat application to protect the weave from UV degradation. We advise on finish options when you call.

Condition and Inspection

Every set of carbon fiber fenders for G37 coupe that ships from our facility goes through a hands-on inspection before packaging.

What We Check Before Every Unit Ships

• Full visual inspection of carbon fiber surface for delamination, bubbles, or voids in the layup
• Gel coat surface inspected for chips, cracks, or surface damage
• Mounting tabs and points inspected for cracks or damage
• Fender arch profile checked against factory reference dimensions
• Body line alignment points inspected for consistency between driver and passenger sides
• Vent openings inspected for clean cut edges on vented configurations
• Hardware inspected where included with the unit
• Overall fitment quality graded and documented before packaging

Carbon fiber layup quality and mounting tab integrity are the two most critical inspection points on aftermarket carbon fiber fenders. We document both before every unit ships. You know what you are getting before the order is processed.

Vehicle Compatibility

The G37 aftermarket fenders fit the following factory applications:

• Infiniti G37 Coupe, 2008 to 2013

Before ordering, confirm your model year and body style. The G37 coupe and G37 sedan use different fender designs. In addition, the G37 coupe and Q60 coupe, which replaced the G37 in 2014, use different body panels. Confirm your specific application before ordering.

Build Compatibility Notes

For track and time attack applications, confirm fender liner clearance with your suspension setup before ordering. Wide fenders on aggressive coilover and camber settings may require fender liner modification or removal for clearance at full suspension travel. Confirm your specific wheel, tire, and suspension geometry before ordering to make sure the fender width increase is sufficient for your fitment goals.

Installation Notes

Mounting

The Infiniti G37 carbon fiber fenders use the factory OEM mounting point locations. On most applications, installation follows the same process as a factory fender replacement. Remove the factory fender using the OEM mounting hardware locations, transfer or replace hardware to the carbon fiber unit, and confirm body line alignment before final torque on all mounting points.

Paint Preparation

Most units ship with a gel coat finish ready for paint. Before painting, lightly sand the gel coat surface with 320 to 400 grit to improve primer adhesion. Apply a quality automotive epoxy primer before color coat. Carbon fiber panels have low thermal mass compared to steel and heat up quickly under direct sunlight, which affects paint adhesion on some lower quality primers. Use a primer rated for composite substrates for best results.

Fender Liner

Factory fender liners may require trimming on the inner edge for clearance with the widened fender arch. Confirm fender liner fitment before completing installation. Some builds run without inner fender liners entirely on dedicated track cars. For street use, retaining the liner protects the engine bay from road debris.

Body Line Alignment

After installing the carbon fiber fenders, confirm body line alignment with the hood and front bumper before driving the car. Carbon fiber fenders from quality suppliers like Fly1 align closely to factory body lines. However, minor adjustment at the mounting points is normal during installation and is part of the fitting process.
