Specifications
The rear diffuser is where the car either looks finished… or looks like it’s missing the last 20%. This ASTO carbon fiber diffuser for the G20 M340i LCI is sculpted to add a deeper, more aggressive rear profile with defined fins and a sharper lower edge—so the back of the car looks wider, lower, and more purpose-built.
And because this is ASTO, it’s not just carbon for the sake of carbon. A clean, engineered lighting detail that sits inside the design language (not glued onto it). Clean by day. Razor-sharp after dark. Built to match the rest of the ASTO kit system so your front, side, and rear speak the same visual language.
