05-09 GT/CS Race Front Splitter

S197 Full-Depth ACM Front Splitter (2005-2009 GT/CS)

This ACM Front Splitter is precision-engineered specifically for the 2005-2009 Mustang GT/California Special (GT/CS) front bumper. Designed to complement the aggressive, lower-fused styling of the factory California Special fascia, it delivers an intimidating, track-focused profile alongside the elite durability required for daily street driving.

Unlike budget "splitter lips" that only follow the front edge of the bumper, this is a true full-depth splitter that provides real aerodynamic benefits and under-car protection.

Complete Under-Tray Protection

The design extends all the way back under the GT/CS front bumper, creating a smooth, flat surface that optimizes airflow under the vehicle. This also provides a secondary layer of armor for lower engine components against road debris.

• Maximum Surface Area: By covering the entire underside of the California Special front fascia, this 6mm ACM panel provides a massive increase in structural rigidity compared to thin, edge-mounted trim pieces.

• Rock-Solid Mounting: The full-depth design allows for multiple secure mounting points across the underside of the chassis, ensuring the splitter stays level, flat, and effective even under high aerodynamic loads.

Product Highlights

• GT/CS Specific Geometry: Specially contoured and engineered from the ground up to follow the distinct lines and curves of the 2005-2009 California Special bumper, extending the front profile for a lower, wider appearance.

• Structural Integrity: Constructed from 6mm Aluminum Composite Material (ACM). It is incredibly stiff to resist high-speed buffeting, yet lightweight enough to avoid unnecessary stress on your front fascia.

• The "Scrape-Safe" Choice: Since S197s often sit low—especially with the deeper GT/CS bumper—resilience is key. While carbon fiber shatters and plastic cracks, ACM remains resilient, offering the perfect balance of a show-quality finish and real-world toughness.

Fitment & Compatibility

• Perfect Match: This splitter is engineered exclusively for vehicles running the OEM 2005-2009 GT/California Special (GT/CS) front bumper cover or exact replicas. It aligns flawlessly with the unique squared-off chin profile of the CS fascia.

Installation Requirements & Disclaimer

These splitters are engineered for enthusiasts who demand real-world durability and performance. Because of the high aerodynamic loads generated, installation is not a simple "bolt-on" process. Please review the following requirements and check the install instructions at the end of the description.

• Drilling Required: To properly secure the splitter, drilling through the factory GT/CS bumper cover is necessary. Stainless steel hardware is provided for these attachment points.

• Chassis Mounting is Essential: For highway speeds or track use, the splitter must be chassis-mounted. At a minimum, splitter rods should be attached to a rigid structural point of the vehicle.

• Buyer Discretion: Various methods exist to achieve a rock-solid chassis mount (custom brackets, support rods, etc.). The specific hardware and method chosen to bridge the gap between the splitter and the vehicle frame are at the discretion and responsibility of the installer.

• Speed Rating: Structural integrity of the splitter or the bumper cover cannot be guaranteed if the unit is not properly supported. For high-speed driving, ensure mounting points are reinforced to the vehicle chassis.

Professional installation is recommended.
