Duraflex 108979 1997-2003 BMW 5 Series E39 4DR Duraflex GT-S Roof Wing Spoiler - 1 Piece (S)

The Duraflex 108979 GT-S Style Roof Wing Spoiler is a one-piece fiberglass reinforced plastic (FRP) rear wing spoiler designed to add aggressive, sporty styling to the BMW 5 Series E39 4-door sedan. Engineered with an aerodynamic profile, this roof-mount wing enhances the visual stance of the vehicle while contributing to improved airflow management at speed.

Key Features:

• Material: Hand-laid, high-quality 6 oz. FRP (Fiberglass Reinforced Plastics) construction using Duraflex's proprietary blend of fiberglass, plastic, and flex resins for superior durability and flexibility
• Style: GT-S roof wing design — a sportier, elevated profile compared to traditional trunk lid spoilers
• Finish: Ships with a black gel coat surface ready for professional prep, prime, and paint to match any vehicle color
• Quantity: 1 Piece
• Trim: 4-Door Sedan models only
• Installation Difficulty: Medium — professional body shop installation strongly recommended
• Mounting Hardware: Not included; OEM-style fasteners and custom brackets may be required for secure mounting

Installation Notes: As with all Duraflex FRP components, minor surface imperfections such as waves, pinholes, or uneven edges are normal characteristics of hand-finished fiberglass and are addressed during professional prep and paint. All parts should be dry-fitted before any mounting holes are drilled. Cutting or shaping of the fiberglass may be required to achieve optimal fitment.

The Duraflex 108979 is an ideal choice for BMW enthusiasts seeking to personalize the appearance of their E39 5 Series with a distinctive, motorsport-inspired roof wing at an affordable price point.
