BMW 1 Series, M135i F40 & F70 Gloss Black Performance Rear Wing Spoiler by FORM (2019+)

Elevate the rear styling of your BMW 1 Series, M135i F40 & F70 with the Gloss Black Rear Wing from FORM. Engineered for direct OEM fitment, this spoiler delivers the aggressive silhouette of a track-spec car with the quality and finish expected from a premium aftermarket upgrade.

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
• Finishes the rear profile with a purposeful, motorsport-inspired look
• 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
• Backed by FORM Industries — a trusted name in OEM-level aftermarket upgrades for modern performance cars

Construction: Pressed in durable ABS plastic with a multi-stage gloss black paint finish — primed, base-coated, and clear-coated to OEM automotive standards. The finish is deep, reflective, and paint-matched to the BMW Black Sapphire / equivalent OEM darks for seamless integration on factory-black cars.

Vehicle Compatibility: Engineered for the BMW 1 Series, M135i F40 & F70, model years 2019+. 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.

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.
