M4 Style Carbon Fiber Trunk Spoiler - BMW F32 / F33 / F36 4 Series

Upgrade your BMW F32, F33, or F36 4 Series with our M4 Style Carbon Fiber Trunk Lip Spoiler. Featuring a 2x2 gloss carbon fiber weave, it adds a clean, sporty look while complementing the factory body lines. Manufactured from high-quality carbon fiber and finished with a UV-resistant clear coat, it is built to resist fading, road debris, and everyday weather conditions. Installation uses automotive-grade 3M adhesive, though professional installation is recommended for the best fit and finish. Please note that custom-made products are not eligible for returns or exchanges.

Installation Protocol

Step-by-step procedure

01

Wash the trunk lid with soap and water, dry fully, then wipe the mounting area with the included alcohol prep pad. Allow 30 seconds to evaporate before proceeding.

02

Hold the spoiler over the trunk lid without peeling the adhesive backing. Confirm flush alignment and familiarize yourself with the correct positioning before committing.

03

Position the spoiler using the OEM trunk lid mounting points. Confirm the base sits flush with no visible gap or overhang along the full width of the trunk edge.

04

Remove the protective film from the 3M adhesive tape. Avoid touching the exposed adhesive with bare fingers to maintain full bond strength.

05

Lower the spoiler onto the trunk lid in the confirmed position. Press firmly across the entire base for 30–60 seconds with even pressure from edge to edge.

06

Do not wash the vehicle or expose it to rain for 24 hours after installation. Full adhesive cure is achieved after this period, creating a weather-resistant bond.

Learn About Our Process
01

Genuine Carbon Fiber Layup

Every Bimmer Plug trunk spoiler is constructed from authentic 2x2 twill weave carbon fiber, not ABS with carbon vinyl overlay. The layup process aligns fiber strands under controlled tension to produce consistent weave symmetry across the full panel surface. Hand finishing ensures each unit meets visual and structural standards before it ships. BMW enthusiasts who inspect their parts closely will find panel to panel weave consistency and edge definition that reflect the quality of the raw material and the care of the build process.

02 / CRAFT DETAIL

UV Sealed Surface Protection

Carbon fiber without proper UV protection will yellow, haze, and lose its gloss finish within one to two seasons of sun exposure. The Bimmer Plug M4 Style Trunk Spoiler is finished with a multi layer UV resistant clear coat applied over the carbon weave to create a sealed, durable surface barrier. This protects the fiber structure from UV induced degradation, surface oxidation, and light abrasion. The clear coat also provides the deep gloss depth that distinguishes real carbon fiber from vinyl wrapped alternatives, and maintains it through years of outdoor exposure.

Explore Standard
03 / VALIDATION

Pre-Ship Inspection Standard

Each trunk spoiler is individually inspected before it leaves the facility. The inspection process covers weave alignment uniformity, clear coat surface quality, edge finish consistency, and fitment geometry verification against F32/F33/F36 OEM trunk lid dimensions. Units that do not pass surface and fitment inspection are withheld from shipment. This pre-ship standard exists because BMW owners who invest in genuine carbon fiber upgrades expect components that arrive ready to install, not components that require rework or return. Manufacturer's Warranty applies, contact support for coverage details.
