Carbon Fiber Rear Trunk Spoiler for BMW F33 4 Series & F83 M4 Convertible (2014-2019)
A vehicle-specific carbon fiber trunk spoiler moulded for the convertible boot lid of the F33 and F83 M4. The convertible deck lid has a different shape from the F32 coupe, so a spoiler cut for this body sits flush along the trailing edge instead of leaving gaps at the corners. It is built from premium 3x3 twill carbon fiber under a UV-resistant high-gloss coating, keeping weight low while giving the deep, unmistakable carbon weave finish, and it mounts as a direct replacement for the factory spoiler with no cutting or modification.

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.
