If you own a Porsche 997 GT2, the side skirts are a key aerodynamic and visual component. Replacing them requires the correct part number to ensure perfect fitment and performance. This guide provides the OEM part numbers for 997 GT2 side skirts, explores aftermarket alternatives, and offers practical buying advice.
OEM Part Numbers for 997 GT2 Side Skirts
The factory side skirts on the 997 GT2 are unique to that model, blending function with the aggressive GT2 styling. Porsche offers these as replacement parts through its dealership network and online parts retailers. The official part numbers are:
- Left side skirt: 997 504 987 01
- Right side skirt: 997 504 988 01
These numbers correspond to the complete side skirt assembly, including the mounting hardware and any attached trim. They are designed specifically for the 997 GT2 (model years 2007–2009) and are not interchangeable with standard 997 Carrera or Carrera S side skirts due to different shapes and mounting points.
What’s Included in the OEM Assembly
The OEM side skirt part numbers include the plastic skirt body, the integrated air deflector lip, and the necessary clips and screws. Some suppliers may list additional sub-components:
- Side skirt grille (left): 997 504 657 00
- Side skirt grille (right): 997 504 658 00
- Side skirt mounting kit: 997 504 249 00 (includes clips, screws, and gaskets)
If your original side skirts are damaged or missing pieces, these separate parts may be needed. Most owners opt for the complete assembly to simplify installation.
How to Verify Your Part Number
Double-check your vehicle’s production date and VIN before ordering. The 997 GT2 had a mid-cycle update in 2008 (Model Year 2009), but the side skirts remained unchanged. However, if your car has been modified or repainted, confirming fitment with the parts department is wise. Use an online Porsche parts catalog with your VIN to get exact match.
Aftermarket Side Skirt Options
Several aftermarket manufacturers offer side skirts for the 997 GT2 that match or exceed OEM appearance and function. These are popular among owners seeking lighter materials or more aggressive styling.
Carbon Fiber Side Skirts
Carbon fiber is a common upgrade because it reduces weight and adds a track-oriented look. Reputable brands include:
- Vorsteiner: Their 997 GT2 carbon side skirts are made with pre-preg carbon fiber and offer a direct replacement. They resemble the OEM shape but feature a slight design tweak for improved airflow. Part numbers vary by vendor, so confirm compatibility.
- Manthey Racing: Known for GT racing parts, Manthey offers carbon side skirts designed for the 997 GT2. These are often lighter than stock and come with installation hardware. Use their official site or authorized dealers to order.
- Taylormade: Another respected brand, Taylormade produces fiberglass and carbon options. The part numbers are specific to their product line and available through their catalog.
Fiberglass Side Skirts
Fiberglass is a budget-friendly alternative to carbon fiber. It is heavier but still lighter than OEM plastic. Brands like Duraflex and AeroCatch offer fiberglass side skirts that replicate the OEM shape. Fitment may require minor adjustments, so professional installation is recommended.
Aftermarket vs. OEM: Pros and Cons
- OEM: Perfect fit, factory appearance, includes all hardware. More expensive, plastic material can be heavy.
- Aftermarket carbon fiber: Lighter, unique look, often expensive. May require painting or clear coating.
- Aftermarket fiberglass: Affordable, but can be brittle and may need modification to fit.
Consider your budget and priorities. If your car is a daily driver, OEM durability may be preferred. For track use, carbon fiber’s weight savings offer a real benefit.
Compatibility Considerations
Not all side skirts labeled as “997 GT2” will fit every variant. Be aware of these factors:
Model Years
The 997 GT2 was produced from 2007 to 2009. All OEM side skirts are identical across these years. Aftermarket options may have minor revisions, so check the product description for year range.
Coupe Only
The 997 GT2 was only available as a coupe. These side skirts will not fit the 997 convertible (Cabriolet) or Targa models because of different rocker panel designs.
Painting and Finishing
OEM side skirts come in a primer-like black finish and must be painted to match your car’s color. Aftermarket parts may arrive painted or unpainted. Ask the seller about the surface finish. Unpainted parts need sanding, priming, and painting—add that cost to your budget.
Installation
Replacing side skirts is a moderate DIY job if you have mechanical skills. The OEM skirts are held on by clips and bolts along the bottom edge. Aftermarket kits often include instructions. For a flawless fit, a body shop can handle painting and mounting.
How to Purchase Side Skirts
You can buy 997 GT2 side skirts from:
- Porsche dealerships: Order by part number. Expect a wait if not in stock. Price is typically higher than aftermarket.
- Online OEM parts retailers: Sites like Pelican Parts, Suncoast Parts, or our local Porsche specialist (search “Porsche OEM parts”). They often discount from MSRP.
- Aftermarket websites: Direct from manufacturers or authorized distributors. Be wary of counterfeit carbon fiber; buy from established brands.
- Porsche forums: Classifieds may have used OEM or aftermarket skirts. Verify condition and ask for part numbers.
Important: When buying used, inspect for cracks, missing tabs, or repaired damage. OEM skirts can be brittle after years of UV exposure.
Final Recommendation
For most owners, the best path is to purchase OEM side skirts with the part numbers 997 504 987 01 (left) and 997 504 988 01 (right). They guarantee fitment, retain the car’s original character, and are readily available. If you want lighter weight and a track-inspired look, invest in quality carbon fiber from Vorsteiner or Manthey Racing. Avoid cheap fiberglass skirts unless you’re on a tight budget and are prepared for possible fit issues.
Before ordering, confirm the part number with your VIN and decide whether you need the full assembly or just the skirt. With the correct part number, your 997 GT2 will maintain its iconic stance and aerodynamic function.
