Description

The Kies Motorsports M4 Inspired Trunk Spoiler provides an aggressive, M4 aesthetic for your BMW G20 3 Series sedan (2019+) and G80 M3 (2021+). Crafted from carbon fiber, this spoiler draws inspiration from the iconic F8X generation M cars, offering a significant styling upgrade over standard trunk spoilers. Designed for a broad range of G20 models including the 320i, 330i, 330e, m340i, 318d, 320d, and 330d, this trunk lip also fits the G80 M3. Importantly, it does not fit the G21 wagon/touring models. Furthermore, the M Sport package is not a prerequisite for installation, meaning base model G20 sedans can also benefit from this enhanced styling. This carbon fiber trunk spoiler is presented as an excellent initial modification for enthusiasts looking to personalize their vehicle. It aims to add a dynamic visual element to the stock 3 Series, blending the contemporary performance of the G20 with the desirable styling cues of the M4.
