BMW M3 E92 Prepreg Dry Carbon Fiber CS Trunk Lid

For BMW M3 E92 Coupé (2012-2013 CS limited), this Prepreg Dry Carbon Fiber CS Trunk Lid draws from the aggressive rear silhouette of the factory M3 CS Competition Package (444 hp). Manufactured in Europe and quality-controlled by BYC Performance.

The S65B40 4.0L V8 NA tuned to 444 hp in 2012-2013 CS form represents one of the final E92 Coupé limited editions. Carry the CS finale identity of the last naturally aspirated M3 in real carbon.

Key Features

• Lightweight: Noticeably lighter than the OEM steel trunk lid.
• OEM Mounting: Direct fit to factory E92 Coupé hinges.
• 2x2 Twill Carbon Weave: High-gloss UV-protective clear resin.

Prepreg Dry Carbon vs. Wet Carbon

Prepreg carbon is autoclave-cured under high heat and pressure → a more consistent weave, a controlled resin ratio, the production method widely chosen in motorsport.
