APR Performance Carbon Fiber Rear Spats 2015-2021 WRX / 2015-2021 STI

APR Carbon Fiber Rear Spats 15-21 Subaru WRX / STI | Lightweight Carbon Fiber | Aerodynamic Rear Bumper Skirts

Overview

The APR Carbon Fiber Rear Spats are precision-engineered aerodynamic components designed specifically for the 2015-2021 Subaru WRX and WRX STI models. These rear bumper skirts attach to the lower sides of the rear bumper to improve high-speed stability by reducing lift generated at the vehicle’s rear. Ideal for enthusiasts seeking enhanced handling and traction during spirited driving or track use, these spats help manage airflow to keep the car planted through corners.

Crafted from high-quality pre-preg carbon fiber composites, APR focuses on lightweight strength and durability. The vehicle-specific design ensures a seamless OEM+ fitment that integrates cleanly with the factory rear bumper lines. This attention to detail reflects APR’s commitment to functional aerodynamics without compromising the refined appearance Subaru owners expect.

By preventing air from rolling underneath the car at the rear corners, these spats reduce aerodynamic lift, which translates to improved rear-end grip and stability at speed. This aerodynamic tuning is especially beneficial for WRX and STI drivers pushing their cars on track or during aggressive canyon runs, where every bit of traction and control counts.
