Overview

The BMW E46 Ducktail Spoiler by Rendition is a lightweight, low-profile rear wing designed to complement the factory body lines of your E46 Coupe or Sedan. Built with performance and subtle styling in mind, it follows the original bootlid curvature with millimeter precision—nothing looks out of place.

This spoiler improves rear-end aerodynamics without disrupting the clean OEM silhouette. Thanks to our ultra-accurate 3D-scanned data, it sits flush with minimal gaps, meaning less adhesive is needed, and no trimming or reshaping is required.

Available in two configurations—an all-in-one carbon fiber version or a modular kit for easier shipping and custom bodywork—this piece was made for enthusiasts who want a OEM+ look with real-world performance gains.

Main Feature

✅ Aerodynamically functional design enhances downforce while maintaining a low drag profile
✅ Precisely molded from 3D scan data for perfect fitment with zero visual gaps

✅ Clean OEM+ styling that follows the natural trunk curve of the E46 Coupe or Sedan
