BMW G82 G83 M4 V2 Full Dry Carbon Fiber Rear Bumper Corner Splitter Extensions 2021-2026

Upgrade the rear-end appearance of your 2021-2026 BMW G82 M4 Coupe or G83 M4 Convertible with these V2 Full Dry Carbon Fiber Rear Bumper Corner Splitter Extensions. Designed to mount underneath the original rear bumper corner extensions, these add-on splitters create a more aggressive, performance-inspired appearance while retaining the factory bumper styling.

Constructed from 100% genuine full dry carbon fiber, these lightweight splitters feature a premium 3K carbon fiber weave and a hard UV-protective clear coat. Unlike decorative carbon-look overlays, each extension uses a full carbon fiber structure. The thin, flat V2 design adds a distinctive lower edge beneath the original rear corner extensions while maintaining a refined carbon fiber appearance.

Designed as direct add-on components, the pair includes pre-applied double-sided adhesive tape and pre-drilled mounting holes for straightforward installation. The splitters attach underneath the factory rear bumper corner extensions using the original fasteners, which must be removed and reused. No additional vehicle modifications are specified. Professional installation is recommended for proper alignment and secure attachment.
