Thoroughly clean and dry the trunk lid surface. Remove any existing spoiler or debris.

02

Secure the drilling template with masking tape. Center-punch marked locations. Verify alignment carefully — drilling is permanent.

03

Drill through trunk lid at marked locations. Deburr edges and apply rust inhibitor to exposed metal immediately.

04

Place spoiler over holes without hardware. Verify flush fitment and zero gap at all trunk lid contact points.

05

Apply thread-locking compound to fasteners. Install hardware and torque to spec. Do not overtighten on carbon fiber.

Learn About Our Process
01

Authentic Carbon Fiber Layup

Every PSM High-Kick Spoiler is constructed using genuine 2x2 twill weave carbon fiber fabric — the same weave specification used in OEM BMW M carbon programs and professional motorsport applications. The carbon layers are hand-laid into precision molds and vacuum-infused with aerospace-grade epoxy resin to eliminate air voids and ensure uniform fiber density across the entire panel. This process produces a structurally consistent, lightweight part that genuine carbon fiber enthusiasts can distinguish immediately from inferior fiberglass or carbon-wrapped alternatives. The result is a spoiler that is both visually authentic and structurally superior.

02 / CRAFT DETAIL

Multi-Layer UV-Protective Clear Coat

The carbon fiber substrate is finished with multiple layers of high-gloss UV-resistant clear coat applied in controlled conditions. UV degradation is the primary cause of carbon fiber yellowing and surface haze on aftermarket panels — particularly in high-sunlight climates and track environments. The clear coat formulation used on this spoiler is designed to maintain optical clarity and gloss depth through extended UV exposure. Surface hardness resists light road debris, car wash abrasion, and chemical contamination from fuel, brake dust, and detailing products. The finish is inspected before shipping to ensure zero orange peel, runs, or surface defects.

Explore Standard
03 / VALIDATION

Fitment-Validated Before Shipment

Each spoiler is test-fitted against G80 M3 and G20 3-Series trunk lid templates before shipment to verify mounting hole alignment, panel gap consistency, and profile accuracy. The high-kick geometry must sit flush at the trunk lid surface with no rocking, shimming, or gap variance — fitment that only comes from production molds engineered specifically for these chassis codes. Hardware included with each spoiler is grade-matched to the mounting requirements of the carbon panel. Manufacturer's Warranty applies — contact Bimmer Plug support for coverage details.

Features & Specifications

01 Premium

Genuine Carbon Fiber

Real 2x2 twill weave carbon fiber construction — not ABS plastic or fiberglass. The structural weave pattern is visible through the high-gloss clear coat, delivering the authentic depth and tactile quality that BMW enthusiasts demand from a premium aero upgrade.

02 Verified

PSM High-Kick Profile

Inspired by PSM Dynamic's motorsport aero program, the aggressive high-kick ducktail geometry makes an immediate visual statement. The elevated rear lip profile adds rear downforce character and transforms the G80 M3 and G20 3-Series silhouette from refined to race-intent.

03 Precision

UV-Resistant Gloss Finish

A multi-layer high-gloss clear coat is applied over the carbon weave, providing protection against UV-induced yellowing, surface oxidation, and road contamination. The finish maintains showroom-quality gloss through long-term daily driving and track use.

04 Complete

G80/G20 Precision Fitment

Mounting hardware and panel geometry are engineered specifically for the G80 M3 and G20 3-Series trunk lid. Factory contour matching ensures flush, gap-free fitment that reads as intentional rather than aftermarket — the standard for a credible carbon build.
