The kidney grille is the most argued-about part on the G8X, and the CSL-style frame is how most owners settle it. This is the version for cars without the front radar sensor — plain cruise control that holds a set speed and nothing more. Not sure? The guide below takes thirty seconds.
A full replacement for the factory kidney grille, built from autoclaved 2x2 pre-preg dry carbon fiber and shaped to the CSL's frame silhouette. It drops into the factory clip positions — the bumper does not come off.
This listing is the non-ACC version. If your car has the front radar sensor, you need the ACC grille instead.
Fits the 2021-2027 BMW M3 (G80) Sedan, M4 (G82) Coupe and M4 (G83) Convertible.
Which One Do I Need?
The two versions differ in the sensor opening behind the grille frame, and they are not interchangeable. There are three ways to tell which you have:
- Look behind the grille. A non-ACC car has open space or a blanking panel behind the kidney frame. An ACC car has a radar module mounted centrally, usually visible as a flat rectangular housing.
- Check how your cruise control behaves. If it simply holds a set speed and does not react to the car ahead, you do not have ACC — this is your version.
- Check your original window sticker or build sheet for Active Cruise Control.
Depending on market and model year, BMW also refers to that system as Active Cruise Control, ACC, or Traffic Jam Assistant. If your car has none of those, this is your version.
Why Autoclave Pre-Preg Dry Carbon Fiber
Pre-preg carbon arrives with the resin already impregnated into the weave at a controlled ratio, so no resin is added by hand during layup — that is what makes it dry carbon. Curing it under heat and pressure in an autoclave consolidates the laminate and drives out trapped air that would otherwise show as flaws in the finished surface. Other processes introduce the resin at the mold, so the ratio is set during layup rather than before it.
A grille frame is the single most-photographed part on this car and sits at eye level on approach. There is nowhere on it for a pinhole or a wandering weave line to hide.
