Installation Protocol

Step-by-step procedure

Professional Installation Recommended

While DIY installation is possible with mechanical knowledge, professional installation is recommended for optimal results and to avoid potential fitment issues.

Book Professional Installation
01

Clean trunk lid and mounting area. Wipe with alcohol prep wipe and allow to dry.

02

Access OEM spoiler fasteners from trunk interior liner. Remove with 10mm socket or Phillips screwdriver. Retain all hardware.

03

Align CS carbon spoiler over OEM mounting holes without fastening. Confirm flush fitment and centered alignment from all angles.

04

Thread OEM fasteners through new spoiler mounts. Tighten evenly — avoid overtightening on carbon fiber surfaces.

05

Open and close trunk several times. Confirm no contact with bodywork. Wipe surface with clean microfiber cloth.

Learn About Our Process
01

Hand-Laid Carbon Fiber Construction

Every CS Style Trunk Spoiler begins with hand-laid 2x2 twill weave carbon fiber sheets, carefully positioned and compressed under controlled curing conditions. This labor-intensive process ensures uniform fiber alignment, consistent resin distribution, and zero voids in the finished part. The result is a structurally sound carbon fiber component that delivers genuine weight reduction and surface integrity — not a carbon-look vinyl wrap or thin veneer over plastic. Each unit is inspected for surface consistency and structural integrity before leaving the production facility.

Explore Standard
02 / CRAFT DETAIL

UV-Resistant Gloss Clear Coat

The carbon fiber surface is finished with a multi-stage UV-stabilized high-gloss clear coat engineered to withstand years of sun exposure, wash cycles, and temperature cycling without yellowing, hazing, or delamination. Standard aftermarket carbon parts frequently exhibit UV degradation within 12-18 months, resulting in a dull, chalky surface. Bimmer Plug's clear coat process provides a durable protective layer that maintains deep gloss depth and preserves the authentic carbon fiber texture — keeping your G80 M3 or G20 3 Series looking sharp season after season.

03 / VALIDATION

Manufacturer's Warranty Coverage

Every CS Style Carbon Fiber Trunk Spoiler is backed by Bimmer Plug's Manufacturer's Warranty covering defects in materials and workmanship. Each unit is inspected prior to shipment for surface quality, structural integrity, and fitment accuracy against the G80 M3 and G20 3 Series mounting specifications. In the unlikely event of a manufacturing defect, Bimmer Plug's support team is available to assess and resolve your claim directly. For full warranty coverage details, contact support@bimmerplug.com or call +1 (949) 229-3397. Manufacturer's Warranty — contact support for coverage details.

Features & Specifications

01 Premium

Authentic CS-Style Aero Design

Engineered to replicate the purposeful trunk profile of the M3 CS — a low-profile ducktail that adds rear visual aggression and subtle downforce enhancement without overwhelming the G80's balanced proportions.

02 Verified

2x2 Twill Weave Carbon Fiber

Hand-laid using genuine 2x2 twill weave carbon fiber with a multi-stage high-gloss, UV-resistant clear coat. The result is an authentic carbon surface that resists UV degradation, maintains gloss depth, and delivers real weight savings over OEM plastic.

03 Precision

Bolt-On OEM Mounting Fitment

Mounts directly to your G80 M3 or G20 3 Series factory trunk mounting points. No drilling, no cutting, no permanent modification. Moderate bolt-on installation in 30-45 minutes using OEM trunk mounting points — no coding, no cutting, fully reversible.

04 Complete

G80 M3 and G20 3 Series Precision Fit

Designed exclusively for the G80 M3 and G20 3 Series chassis. Every contour, mounting hole position, and edge profile is calibrated to eliminate panel gaps and deliver flush, OEM-quality fitment that looks factory-intentional.
