This kit pairs a Heavy Duty pressure plate with a rigid full-face performance disc, delivering a 46 to 87 percent increase in torque capacity over the factory clutch depending on the specific build. Unlike a sprung race disc, the ZM15-HDSD's rigid hub is built for street and light performance use, giving a more direct pedal feel without the segmented chatter of a full race disc. The kit ships with a chromoly XACT Streetlite flywheel so the entire assembly is matched and balanced from the factory.\u003c\/p\u003e\n\u003ch4\u003eKey
