BMW 3 Series G20 / M3 G80 Sedan Carbon Fiber Rear Trunk Spoiler

Carbon Fiber Rear Trunk Spoiler for BMW G20 / G80 M3 Sedan

Give the rear of your sedan a squared-off carbon-fiber accent. The source describes this spoiler as sitting along the flattened rear section of the trunk, where the rear line ends, rather than simply on the upper trunk surface. Compare that mounting location and the full contact footprint with your actual trunk before ordering. This is an exterior styling spoiler, not a replacement trunk lid or complete body kit.

Listed Vehicle Applications

• BMW 3 Series G20 Sedan, Base/M Sport.
• Petrol and plug-in hybrid designations listed: 318i, 320i, 330i, 330e and M340i.
• Diesel designations listed: 316d, 318d, 320d, 330d and M340d.
• BMW M3 G80 Sedan.

Verify years separately for G20 and G80. The detailed source combines both chassis under 2019, 2020, 2021, 2022 and 2023 without a chassis-specific or model-by-year compatibility table. That grouped range does not establish G80 M3 compatibility from 2019 or every named G20 engine in every listed year. The source-listed 316d designation also requires chassis and regional verification. The original title's open-ended 2019+ wording is not confirmation of all later years.

Confirm VIN, production date, regional model year, chassis, trim and trunk contour. Verify facelift and later-year applications individually. Specific G80 Competition, drivetrain and special-edition applications are not separately documented. Existing xi/xDrive references in filter or search tags do not replace checking the exact vehicle.

The detailed fitment specifies Sedan. Touring/wagon, long-wheelbase models, coupe, convertible, M4 and other generations are not confirmed applications. Search tags mentioning coupe, M4 or early G80 years do not establish fitment.

Rear Trunk Mounting Profile

Check that the rear-facing mounting area matches the spoiler's contour. Compatibility with an existing factory or aftermarket spoiler, stacking over another spoiler, removal procedures and coverage of old mounting holes are not established. Verify these details before removing original trim or adhesive.

Material and Finish

• Specified material: 3×3 weave carbon fiber.
• Gloss surface with a double-layer UV-protected clear coating.

The source uses full-carbon wording but does not supply a detailed laminate specification or confirm a dry-carbon process. Dimensions, measured component weight and measured weight savings are not provided. Permanent resistance to fading is not promised.

Package and Attachment

The trunk spoiler and installation tape are listed. Exact molded piece count and tape quantity are not itemized. Screws, brackets, clips and additional adhesive products are not listed as included.

The source describes tape attachment with no modification. Test-fit and verify suitable adhesive retention before installation. Included tape does not establish secure tape-only attachment on every painted, wrapped, repaired or altered surface; do not drill or force a mismatched part into place.

Installation Guidance

Test-fit before removing adhesive backing or disturbing existing trim. Professional installation is recommended if the rear-facing contour, contact area or existing spoiler arrangement is uncertain. Prepare clean, dry contact surfaces and follow the adhesive manufacturer's application-temperature, pressure and curing instructions.

Check full trunk opening and closing clearance, normal latch operation and unobstructed lights, camera, release controls and rear visibility where applicable. Verify secure attachment before driving and recheck according to the installer's guidance. Do not use the spoiler as a trunk handle or lifting point.

Performance Scope

This listing describes an exterior styling upgrade. No measured drag, downforce or vehicle-stability results are supplied, so reduced drag, increased rear downforce and improved handling are not promised.

Is this dry carbon?
The source specifies 3×3 carbon fiber without confirming a dry-carbon manufacturing process.

Is installation tape included?
Yes, tape is listed. Correct fit, surface preparation, curing and secure retention still require checking.
