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. Imported from leading manufacturers around the world 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-inspired aero 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.
Installation Notes
- Open trunk and mark hinge bolt positions.
- Disconnect key microswitch and lighting harness.
- With two people, remove the OEM trunk lid.
- Align CSL trunk lid on hinges.
- Equalize bumper, fender, and roof gaps (to the manufacturer's recommended torque).
- Reconnect lock cylinder and gas struts.
Care & Maintenance
Wash with pH-neutral shampoo. Apply carbon-safe sealant every 6 months. Keep pressure washer 30 cm from surface.
