Porsche 991 911 Left Fender: Parts, Pictures, and Buying Guide

The left fender is a critical body panel on the Porsche 991 911. Whether you're repairing collision damage, upgrading to a wider GT3-style fender, or restoring a project car, choosing the correct part matters for fit, finish, and overall aesthetics. This guide covers everything you need to know about Porsche 991 911 left fender parts, including pictures of common options, material differences, fitment considerations, and purchasing advice.

Understanding the Porsche 991 Left Fender

The Porsche 991 generation (2011-2019) includes several variants—Carrera, Carrera S, 4S, Turbo, GT3, and others—each with slightly different fender designs. The left fender (driver’s side in North America) is not interchangeable across all models without modification. For example, a Turbo fender has wider wheel arches to accommodate larger tires and air intakes, while a standard Carrera fender is more narrow. Additionally, GT3 and GT3 RS fenders have unique vent shapes and wider flares.

When shopping for a left fender, you’ll encounter several key identifiers:

• Model year: 991.1 (2012-2016) vs. 991.2 (2017-2019) have different front fascia designs that affect fender alignment.
• Drivetrain: All-wheel-drive models (Carrera 4, 4S, Turbo) have slightly wider front fenders than rear-wheel-drive versions.
• OEM part numbers: Porsche uses specific numbers such as 991-503-111-11 (left fender for 991.1 Carrera) or 991-503-111-60 for later versions.

Pictures of these fenders show subtle differences in the cutouts for side markers, turn signals, and the front bumper interface. Always verify your exact model and VIN before purchasing.

OEM vs. Aftermarket Left Fenders

OEM Porsche Fenders

Original Equipment Manufacturer (OEM) fenders are made by Porsche or its approved suppliers. They are guaranteed to fit perfectly, come with proper primer or paint-ready surfaces, and include all necessary mounting points and reinforcements. OEM parts are more expensive—typically $600–$1,200 for a left fender depending on the model—but they offer the best alignment and durability. For insurance repairs or concours restorations, OEM is the recommended choice.

Aftermarket Fenders

Aftermarket options range from budget-friendly steel panels to lightweight carbon fiber race parts. Common aftermarket brands include Karbel, Vorsteiner, and D911. Prices can be as low as $200 for a raw steel replacement to over $2,000 for a dry carbon fiber GT3-style fender.

Pros of aftermarket:

• Lower cost for basic replacements.
• Weight savings with carbon fiber or fiberglass.
• Wider shapes for track use or aggressive styling.

Cons:

• Fitment can be inconsistent—panel gaps may require adjustment.
• Some aftermarket fenders lack inner liners, mounting brackets, or corrosion protection.
• Paint preparation may need extra work.

Always ask for pictures of the actual product before buying. Many aftermarket fenders look fine in stock photos but have visible molding imperfections.

Material Choices: Steel, Aluminum, and Carbon Fiber

Steel (OEM Standard)

Most 991 left fenders are made of steel. Steel is strong, easy to repair, and relatively inexpensive. It’s heavy but offers good crash performance. A steel fender weighs around 8–10 pounds. For street cars that won’t see track duty, steel is perfectly adequate.

Aluminum (Some OEM and Aftermarket)

Aluminum fenders are lighter than steel (about 5–7 pounds) and resist rust. However, they are harder to repair—aluminum can crack rather than dent. Some OEM Turbo and GT3 fenders are aluminum, and a few aftermarket manufacturers offer aluminum units. They cost more than steel but less than carbon fiber.

Carbon Fiber (Aftermarket Performance)

Carbon fiber fenders are popular for weight reduction and aggressive looks. A typical dry carbon left fender can weigh as little as 2–3 pounds. They are often used on track-focused builds. However, carbon fiber is brittle and can shatter on impact. It also requires careful paint preparation to avoid spider-webbing. If you’re not chasing track times, carbon fiber is an expensive and fragile choice.

Fitment Considerations

Before buying a left fender, consider these fitment factors:

• Side marker and turn signal cutouts: US-spec cars have orange side markers; Euro-spec may not. Ensure the fender has the correct opening for your region.
• Headlight washer jets: If your car has them, the fender must have the proper hole.
• Front bumper alignment: The fender’s leading edge must match your bumper’s shape. Aftermarket fenders sometimes have a mismatch that leaves a gap.
• Wheel well clearance: Wider fenders may interfere with inner liners or suspension components. Measure your wheel and tire setup.
• Paint-ready condition: Some aftermarket fenders come bare metal or with a thin primer. OEM fenders usually have a high-quality primer that’s ready for paint after a light scuff.

Always request detailed pictures of the fender from multiple angles, especially the inside and edge contours.

Installation Tips

Replacing a 991 left fender is a moderate DIY job, but professional installation is recommended for perfect fitment. Key steps:

1. Remove the front bumper and headlight on the left side.
2. Disconnect electrical connectors for side marker and turn signal.
3. Remove the wheel and inner wheel well liner.
4. Unbolt the fender from the A-pillar, door hinge area, and under the hood.
5. Transfer any brackets or trim pieces to the new fender.
6. Test-fit before painting—check gaps with the hood, door, and bumper.
7. Apply seam sealer and corrosion protection as needed.

If using aftermarket, you may need to elongate bolt holes or shim the fender to align with adjacent panels.

Finding the Right Part (with Pictures)

To see pictures of a Porsche 991 left fender, visit manufacturer websites or part catalogs. Look for high-resolution images showing:

• The full fender from outside and inside.
• Close-ups of mounting points and edges.
• The fender installed on a car (if possible).

Search for part numbers like 991-503-111-11 (991.1 Carrera left fender) or 991-503-111-60 (991.2 left fender). Many online part retailers provide multiple pictures and compatibility charts.

For aftermarket options, search “991 GT3 left fender carbon fiber pictures” to see how different brands style the vents and flares. Compare photos to your car’s current fender to spot differences.

Final Recommendation

For most owners, an OEM steel or aluminum left fender is the safest choice. It ensures perfect fit, durability, and straightforward installation. If you’re on a tight budget, a quality aftermarket steel panel can work, but budget extra time for adjustments. For track cars, a carbon fiber fender saves weight, but only if you are prepared for the higher cost and fragility.

Always request pictures of the specific fender you are buying, and verify compatibility with your exact model and year. A well-chosen left fender will restore your 911’s appearance and maintain its value.
