BMW M3 E90/E92 Prepreg Dry Carbon Fiber CSL Trunk Lid

For BMW M3 E92/E93 (2007-2013), this CSL-styled Prepreg Dry Carbon Fiber Trunk Lid features an integrated ducktail spoiler inspired by classic CSL aero philosophy and bolts directly to factory hinges. Manufactured in Europe and quality-controlled by BYC Performance.

An aggressive rear silhouette worthy of the last naturally aspirated M3 powered by the S65 V8 4.0L NA. Note: No production E92 CSL was ever built (only a 2018 one-off prototype exists); this is a CSL style-inspired aero replica trunk lid.

Key Features

• Prepreg Dry Carbon: Autoclave-cured under high heat and pressure — a more consistent weave.
• Integrated Ducktail: Raised rear lip inspired by CSL lines — no separate spoiler needed.
• Lightweight: Noticeably lighter than the OEM steel trunk lid.
• OEM Mounting: Bolts directly to factory hinges; preserves key cutout and M emblem mounting.
• 2x2 Twill Carbon Weave: High-gloss UV-protective clear resin.

Prepreg Dry Carbon vs. Wet Carbon

Prepreg carbon is autoclave-cured → a more consistent weave, a controlled resin ratio, the production method widely chosen in motorsport. Lighter and stronger than wet-lay parts.

Vehicle Fitment

• BMW M3 E92 Coupé (2007-2013) — S65 V8 NA / CS / GTS
• BMW M3 E93 Convertible (2007-2013) — S65 V8 NA (shares trunk geometry)
• Pre-LCI + LCI all years

Important notes: NOT compatible with E90 Sedan — sedan trunk geometry differs from coupé/convertible. NOT compatible with E46 M3 or F80/F82. No production E92 CSL was built; this is a CSL-styled aero replica.
