Description
Finish the rear profile of your BMW 4 Series & M4 Convertible in style with the Gloss Black Rear Spoiler from FORM. Designed as a precise OEM-level fit, this spoiler adds purposeful lines and subtle downforce to deliver a motorsport-inspired silhouette without compromising factory refinement.
Key Features:
- Direct OEM fitment — retains factory mounting points, wiring connectors, and sensor cut-outs where applicable
- OEM-grade gloss black finish with high-build primer for a deep, mirror-like appearance
- Adds downforce over the rear axle for improved high-speed stability
- Finishes the rear profile with a purposeful, motorsport-inspired look
- Complements the car's existing lines without dominating the silhouette
- Backed by FORM Industries — a trusted name in OEM-level aftermarket upgrades for modern performance cars
Materials: Manufactured in automotive-grade composite with a deep gloss black final finish. The paint is applied over high-build primer for a flawless, orange-peel-free surface that sits cleanly alongside factory gloss-black trim pieces.
Vehicle Compatibility: Engineered for the BMW 4 Series & M4 Convertible, model years 2014-2019, F33 F83. The part uses factory mounting hardware and (where relevant) existing wiring connectors, so a standard install requires no modification to your car's bodywork or wiring loom. Chassis codes matter — please confirm yours matches the listed fitment above before placing your order.
Installation: Fitment is straightforward for an experienced installer using standard hand tools. We strongly recommend installation by a qualified bodyshop or detailer, particularly for exterior components that require panel alignment, adhesive bonding, or painted-surface preparation. Full fitment guidance is provided in the box, and our support team can help confirm the best approach for your specific car.
