Nosta x Gintani Rear Side Extensions – E90 / E92 / E93 M3
Gintani Rear Side Extensions are a premium aero upgrade designed specifically for the BMW E9X M3 platform. Engineered to integrate seamlessly with Gintani rear diffusers, these extensions refine the lower bumper profile and add a sharper, more aggressive rear-end finish.
Proudly American-made in California, each set reflects the quality and craftsmanship Gintani has been known for. Now under Nosta Performance, which owns the rights to all Gintani BMW products, this legacy continues with a renewed focus on performance and precision.
Built for clean fitment and a motorsport-inspired aesthetic, they deliver the perfect balance of subtlety and aggression—making them a key finishing touch for any E9X M3 build.
