15-23 Mustang Rear Side Splitters

Fits: 2015–2023 Mustang (All Models)

These Rear Side Splitters (also known as rear spats) serve as the "missing link" in the S550’s aero profile. They extend the aggressive lines of the side skirts to the rear bumper, creating a continuous, grounded look from front to back.

The Perfect Finishing Touch

• Cohesive Design: These are engineered to flow perfectly with 6mm Main Side Skirts and Rear Diffusers. When paired together, they wrap the entire lower perimeter of the S550 in a unified, track-inspired theme.

• Aggressive Rear Profile: By adding width to the lowest point of the rear bumper behind the tires, these splitters provide a wider, more planted stance when viewed from the rear.

6mm ACM Construction

• Consistency in Quality: While many alternatives utilize flimsy plastic for smaller components, these parts maintain a high standard by using Heavy-Duty 6mm (1/4") ACM.

• Rust-Proof & Heat-Stable: The material will not corrode and is designed to resist warping, even when in close proximity to exhaust tips.

Simple 5-Minute Installation

• DIY Friendly: No complicated brackets or bumper removal is required. These components mount directly to the lower lip of the rear bumper.

• Hardware Included: High-quality self-tapping screws are provided for a secure, "set-it-and-forget-it" installation.

• Precision Fit: Each piece is pre-contoured to match the edge of the 2015–2023 rear bumper perfectly.
