BMW 4 Series & i4 Gran Coupe G26 Pre-Preg Carbon Fibre Rear Spoiler by FORM (2021+)

Complete the rear aesthetic of your BMW 4 Series & i4 Gran Coupe G26 with the Pre-Preg Carbon Fibre 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
• Finishes the rear profile with a purposeful, motorsport-inspired look
• UV-stable clear coat prevents yellowing, fogging, and weave degradation over time
• Complements the car's existing lines without dominating the silhouette
• Adds downforce over the rear axle for improved high-speed stability
• Backed by FORM Industries — a trusted name in OEM-level aftermarket upgrades for modern performance cars

Construction: Built using pre-preg carbon fibre — carbon cloth pre-impregnated with resin, then vacuum-bagged and autoclave-cured under precise heat and pressure. This is the same process used for OEM supercar bodywork and track-homologated race parts. The benefit over cheaper wet-layup carbon is a tighter weave, a more consistent finish, and a clear coat that won't yellow or cloud over time.

Fitment: This product is designed specifically for the BMW 4 Series & i4 Gran Coupe G26, model years 2021+. 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.
