Build Journal

Enhancing a vintage interior.

The original E46 M3 CSL interior was visually appealing, with unique design across exclusive seats and carbon components.

It had a unique set of door sills that are unfortunately discontinued as of 2026.

In this upcoming entry, I will document our carbon door sills; their aesthetics, their options and how they fit.

Cheers,
Matt
