Rear Bumper Splitters Carbon Fiber for 2021+ BMW 3 Series G80 M3
Available in stock (20)
Carbon Fiber Rear Bumper Splitters for 2021+ BMW G80 M3 Sedan — Wet Carbon, Dry Carbon
The BMW G80 M3's wide rear bumper features a prominent lower diffuser section flanked by structured outer rear bumper corners — one of the G80's most performance-forward exterior surfaces. These carbon fiber rear bumper splitters are a direct OEM-replacement for the factory rear bumper outer splitter blades, replacing the factory units with genuine carbon fiber for a sharper rear bumper profile, added lateral rear downforce, and motorsport-grade carbon detail at the G80 M3's most expressive rear exterior surfaces. Three material and condition options to suit your build spec and budget.
Key Features
- G80 M3-Specific Fitment: Direct OEM replacement for the 2021+ BMW G80 M3 Sedan factory rear bumper splitters — bolt-on with self-tapping screws included. No cutting, no modification required. Real-car tested, fitment guaranteed.
- Direct OEM Replacement: Replaces the factory rear bumper outer splitter blades directly — mounts to existing bumper attachment points. Maintains factory rear bumper structure and diffuser integration.
- Rear Downforce: Lateral rear splitter blades at the G80's outer rear bumper corners add rear downforce and sharpen the M3's rear bumper outer profile, complementing the factory diffuser and quad-exit exhaust architecture.
- UV-Resistant High-Gloss Finish: Double-layer UV-protective clear coat on all three variants — locks in carbon gloss and resists fading and surface hazing over time.
- Export-Grade Packaging: Multi-layer shockproof export carton (3 kg gross) ensures safe delivery across international shipping routes.

Ordered the BMW front bumper fog light grille and the fitment was absolutely perfect. Gloss black finish looks factory-fresh and the quality is outstanding. Installation took about 30 minutes — no drilling required. Highly recommend AlchemyRide!

Fast shipping, great packaging, and the part arrived in perfect condition. The grille fits my F23 like a glove — exactly as described. Customer service was also super responsive when I had a fitment question. Will definitely order again.
