The ACT 6-Pad Spring-Centered Race Disc for 2001–2006 BMW M3 (E46) is a high-temperature race disc using ceramic friction for faster, firmer engagement. Heavy-duty torsional dampening springs and a 6-pad layout help absorb heat and smooth engagement on larger clutch sizes, offering a more direct shift feel for track-focused applications while retaining spring-centered damping where needed.
