ACT Heavy Duty Race Rigid 6-pad clutch kit for 2017–2019 Honda Civic Si features ACT's heat-treated diaphragm pressure plate with a 6-pad rigid race disc made from ceramic friction materials and a chrome-moly hub for strength. The lightweight, rigid design promotes quicker shifts and trouble-free service; engagement is harsher but shift response is faster, making this configuration suitable for larger clutch sizes that need greater heat absorption.
