Gloss Black Rear Boot Spoiler — BMW 3 Series G20 & M3 G80 (2019+)

Give your BMW G20 3 Series or G80 M3 a proper motorsport-inspired finish with our gloss black rear boot spoiler. Precision-moulded to the current-generation 3 Series saloon and M3 bootlid, it bolts on with pre-applied 3M adhesive tape — no drilling, no permanent modification, no bodywork required.

The deep gloss black finish contrasts sharply against silver, white, blue, and grey paintwork, and blends seamlessly with black cars for a cleaner, more aggressive rear-end profile.

Direct-fit compatibility:

• BMW 3 Series (G20 saloon) — 2019 onwards, all trims including M340i, M340d, and M Sport
• BMW M3 (G80) — 2021 onwards, including M3 Competition

⚠️ Not compatible with:

• G21 Touring (estate) — different bootlid shape

How to fit:

1. Wash the bootlid area thoroughly and dry
2. Clean the mounting area with isopropyl alcohol to remove all wax, polish, and residue
3. Warm both the bootlid and the spoiler underside to around 20–25°C (leave the car in a warm garage for an hour before install)
4. Peel the adhesive backing from the spoiler
5. Position carefully, then press firmly along the entire contact edge for at least 30 seconds
6. Leave the car undisturbed for 24 hours before washing or driving in rain to allow the adhesive to fully cure

Fitment tip: For best long-term adhesion, avoid installing in cold or wet conditions. Ideal install temperature is above 15°C.
