GTR Carbon Fiber Duckbill Spoiler – BMW G80 M3 / G20 3 Series

Originally developed under Eterna Bespoke, the in-house product development division of Eterna Motorworks, the GTR Duckbill Spoiler made its debut as part of the G80 M3 GTR Widebody Program. Constructed from carbon fiber, the GTR Duckbill Spoiler was designed for those seeking a more substantial rear profile without committing to a full wing. Its raised profile extends beyond a traditional trunk spoiler, giving the rear of the G80 M3 and G20 3 Series a more aggressive presence while maintaining a clean, integrated design. The GTR Duckbill can be paired with the complete GTR Widebody Program or installed independently on any compatible BMW G80 M3 or G20 3 Series. The GTR Widebody Kit is not required for installation. ⸻ Key Features: • Originally developed for the G80 M3 GTR Widebody Program • Carbon fiber construction • Raised, extended duckbill profile • Designed and manufactured in the USA Available as part of the complete GTR Widebody Program — click here to explore the full conversion. ⸻ Compatible Models: • BMW G80 M3 (2021–Present, Sedan) – Base & Competition • BMW G20 3 Series (2019–Present, Sedan) Designed specifically for compatible BMW G80 and G20 sedan applications. ⸻ What’s Included: • (1) GTR Carbon Fiber Duckbill Spoiler • Installation hardware not included ⸻ SHIPPING: • Worldwide shipping and local pickup available • Made to order; production and shipping times vary per order ⸻ Professional installation is highly recommended.
