Karbonius M3 E46 CSL Trunk Lid

Description

Karbonius CSL Style Carbon Fibre Trunk Lid – BMW E46 Coupe

Inspired by the original BMW CSL part (OEM Ref: 41-00-7-895-884), this Karbonius CSL Style Trunk is a high-quality replica made from 100% prepreg carbon fibre, cured in an autoclave to deliver outstanding structural integrity, low weight, and excellent finish quality. Whether you’re building a CSL-style road car or a full track build, this is the boot lid your E46 deserves.

With an exterior weight of just 5.5 kg — nearly 50% lighter than the OEM steel trunk — this is one of the most impactful ways to shed weight from your E46’s rear end. Available in primed, ready-to-paint finish or with a visible 2×2 carbon weave and UV-protected gloss clear coat, it blends OEM aesthetics with motorsport function.
