The SPEC ST-Trim twin disc clutch kit fits BMW M3 models from 2012–2017, BMW M2 from 2015–2017, and BMW M4 from 2013–2017. Packaged as a twin-disc ST-Trim kit, it replaces the factory clutch assembly to provide a higher clamp capacity and stiffer engagement profile suited to high-load street or track use where a multi-plate clutch is required for improved torque handling.
