Overview

The Rendition E39 Ducktail Spoiler is built for owners who want to sharpen the rear of their 5-Series without losing its refined luxury character. Unlike oversized aftermarket wings, this design sits low and clean, following the trunk’s natural arc with just the right lift. The result is a subtle, period-correct accent that looks like it could have come from BMW’s own design studio: understated, sporty, and seamlessly in tune with the E39’s executive-class lines.

Main Feature

✅ Low-profile height: subtle lift that enhances luxury rather than aggression

✅ 3D-scanned geometry: precise contour match to the E39 trunk lid

✅ OEM+ aesthetic: period-correct lines that look factory-clean

✅ Lightweight, durable composite with UV and heat resistance

✅ Maintains trunk function and badge visibility

✅ Finishes available: raw PC for paint or real carbon fiber

Installation

✅ Carbon Fiber version installs with ultra-thin double-sided tape (recommended: 3M VHB, under 1mm thick)
✅ Kit version assembles using alignment keys and adhesives—designed to be foolproof
✅ No drilling or modification required
✅ Clean both surfaces thoroughly before install for best adhesion
