ACT Heavy Duty Race Rigid 6 Pad Clutch 2006-2017 WRX / 2005-2012 Legacy GT / 2006 Spec B / 2006-2008 Forester XT

The SB5-HDR6 kit combines ACT’s Heavy Duty pressure plate with a 6-pad rigid race disc for aggressive race performance. The diaphragm-style pressure plate increases clamp load, reduces deflection, and maximizes clutch life. The high-quality ceramic disc with a heat-treated chrome-moly hub offers strength, durability, and quick, precise engagement. Rigid 6-pad construction allows faster shifts and better heat absorption in larger clutch sizes, though engagement is harsher and may increase spline wear.
