Glossy Black Rear Trunk Spoiler for BMW 3 Series G20, G28 & G80 M3 Sedan 2019-2023

Glossy Black Rear Trunk Spoiler for BMW 3 Series G20, G28 & G80 M3 (2019-2023)
A moulded rear trunk spoiler developed from the factory G20 trunk shape, so it aligns with the car's own rear curvature instead of looking like an add-on. It gives the rear end a wider, more planted stance while extending airflow over the trunk to trim drag and add a little rear downforce for steadier high-speed behaviour. The gloss finish is protected by a UV-resistant clear coat, and it fixes to the trunk with automotive-grade double-sided tape, so there is no drilling and no bodywork.

Ordered the BMW front bumper fog light grille and the fitment was absolutely perfect. Gloss black finish looks factory-fresh and the quality is outstanding. Installation took about 30 minutes — no drilling required. Highly recommend AlchemyRide!

Fast shipping, great packaging, and the part arrived in perfect condition. The grille fits my F23 like a glove — exactly as described. Customer service was also super responsive when I had a fitment question. Will definitely order again.
