The Exedy Stage 2 Cerametallic clutch kit for 2004–2011 Mazda 3 employs a thick disc to boost heat capacity and durability for street, rally and occasional track use. Cerametallic friction resists slipping and fading under high‑power abuse and puck designs often have lower inertia than stock discs. The kit includes a sprung center damper to smooth engagement and cites a 225mm disc with 22T/24.3mm spline.
