What Owners Say
Owners and enthusiasts consistently praise the ACT Heavy Duty Street Clutch Kit for its significantly increased torque capacity and improved durability over stock, with engagement that's immediate and grabs firmly. The pedal feel is noticeably heavier but manageable for street use, though drivers report a learning curve during the first 2,000 miles as the clutch breaks in and engagement transitions from feeling like a "lightswitch" to smoother operation. Some note the kit produces noticeable noise, particularly on naturally aspirated applications where the added clamping force may be more than necessary. Despite the break-in period and firmer pedal, the ACT Heavy Duty kit has earned solid recognition among performance enthusiasts seeking a reliable upgrade that handles increased power.
