The Clutch Masters FX250 rigid disc clutch kit for select BMW applications (including 2008–2009 135i and 2007–2010 335i twin‑turbo models) uses a Power Plus I heavy‑duty pressure plate and Fiber‑Tough friction material to increase holding capacity roughly 110%. Intended for spirited street driving and occasional track use, it balances higher clamp capacity with street‑friendly engagement characteristics.
