Eterna Motorworks was the first in the world to debut the GTR Race Widebody Kit, setting a new benchmark in the G82 platform and dominating the aftermarket scene with multiple award-winning SEMA builds ever since.

Transform your G82 M4 Coupe into a true motorsport-inspired icon with the GTR Race Style Widebody Kit. This kit is engineered to fit all BMW G82 M4 Coupes, delivering an aggressive, race-ready presence that turns heads and dominates show floors.

Crafted in the USA using advanced FRP (Fiberglass Reinforced Plastic) and CFRP (Carbon Fiber Reinforced Plastic) processes, every panel is built for strength, flexibility, and long-term durability. Unlike traditional fiberglass, our FRP technology incorporates flexible resins to reduce cracking and impact damage by up to 75%, all while maintaining a clean gelcoat surface finish ready for paint or prep.
