KHK PSM Style Trunk Spoiler — G20 3 Series / G80 M3 — Overview
The KHK PSM-style trunk spoiler is a direct, no-nonsense upgrade for G20 3 Series and G80 M3 sedan owners who want a sharper, more purposeful rear profile without touching a drill. Modeled after the motorsport-influenced PSM design, the spoiler sits flush along the trunk lid's trailing edge, tightening the car's visual silhouette and adding a subtle aggressive character that the factory lip simply doesn't deliver.
Built from high-grade ABS plastic — the same material class used across OEM exterior trim — this spoiler keeps weight low while offering genuine durability. The material is specifically resistant to UV degradation, surface scratching, and moisture, meaning the gloss black finish holds up through seasonal weather, car washes, and daily highway use without fading or peeling over time.
Installation is designed to be completed at home with no professional help required. Clean the trunk lid surface, mark your placement, peel the pre-applied double-sided tape backing, and press the spoiler firmly into position. A second pass of firm pressure ensures the adhesive bonds fully and the wing sits tight against the body contour — no gaps, no rattle, no damage to your paint or resale value.
This spoiler is confirmed compatible with all 2019–2024 G20 4-door sedan variants, including the 330e, 330e xDrive, 330i, 330i xDrive, M340i, M340i xDrive, and the G80 M3. It is not designed for 2-door or Touring wagon body styles, so verify your specific configuration before purchasing.
