Description

The Extreme Dimensions Duraflex C-Speed Rear Lip Under Spoiler Air Dam is a one-piece aerodynamic enhancement designed specifically for most Subaru Impreza models from 2002 to 2007, including the WRX and STI variants. This rear lip under spoiler improves the vehicle’s rear-end aerodynamics by reducing drag and enhancing downforce, making it an ideal upgrade for Subaru enthusiasts seeking both style and functional performance. Its sleek black finish complements the Impreza’s aggressive stance while providing a subtle yet impactful visual upgrade. Crafted from a proprietary polymer blend combined with hand-laid 6 oz. fiberglass, this air dam balances flexibility and durability. The use of high-quality materials ensures resistance to road debris and weather elements, while the integrated aluminum mesh grille (where applicable) adds a refined touch and protects the undercarriage. Extreme Dimensions focuses on delivering parts that not only look OEM+ but also withstand the rigors of daily driving and spirited use. By improving airflow around the rear bumper area, this rear lip under spoiler reduces aerodynamic lift and can decrease damage rates by up to 75% compared to stock configurations. For Subaru Impreza owners, this means enhanced stability at higher speeds and a more aggressive appearance without compromising reliability. The limited warranty and satisfaction guarantee further underscore the product’s quality and the brand’s confidence in its performance.
