The SPEC E-Trim twin disc clutch kit is for 2008–2012 BMW M3 4.0L 6-speed models. This twin-disc E-Trim option increases torque capacity while aiming to preserve engagement characteristics suitable for aggressive street and occasional track use, providing an upgrade path for the M3’s drivetrain where higher holding capacity is required without excessive drivability loss.
