Description
Complete the rear aesthetic of your BMW 1 Series, M135i & M140i F20 F21 with the Gloss Black Rear Spoiler from FORM. This precision-engineered spoiler bolts directly to the factory boot lid, transforming the car's profile while contributing to rear-end stability at speed.
Key Features:
- Direct OEM fitment — retains factory mounting points, wiring connectors, and sensor cut-outs where applicable
- Adds downforce over the rear axle for improved high-speed stability
- Complements the car's existing lines without dominating the silhouette
- OEM-grade gloss black finish with high-build primer for a deep, mirror-like appearance
- Finishes the rear profile with a purposeful, motorsport-inspired look
- Backed by FORM Industries — a trusted name in OEM-level aftermarket upgrades for modern performance cars
Materials & Construction: Moulded in high-quality ABS composite and finished in a deep gloss black paint, this component is engineered to match OEM panel-fit tolerances while delivering a sharper, more aggressive alternative to the factory finish. The gloss finish resists fading, resists light scuffs, and can be polished to restore showroom shine.
Fitment: This product is designed specifically for the BMW 1 Series, M135i & M140i F20 F21, model years 2011-2019. It integrates with the factory panel lines, mounting points, and (where applicable) electronic systems, meaning no cutting, drilling, or bodywork modification is required for a standard install. Please double-check your chassis code against the listed fitment before ordering — if you're unsure, our support team is happy to confirm compatibility for your exact vehicle.
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.
The FORM Industries Difference: Where many aftermarket brands compete on price, FORM competes on fit and finish. Every part in the catalogue is developed on real cars — not just in CAD — with panel-gap tolerances, material selection, and finishing processes benchmarked against the OEM part it replaces. It's why FORM has become one of the go-to names for BMW M, Audi RS, and Porsche GT owners looking for an upgrade that genuinely measures up.
