ACT XACT Flywheels

This bolt on upgrade for your ND Miata is a Streetlite flywheel, which is considerably lighter than stock and is the most durable flywheel offering from ACT. Materials are properly distributed for maximum strength, lower inertia, good heat tolerance and rigidity. ACT's Streetlite flywheels are preferred for street or road racing/drag racing. ACT flywheels are serviceable and can be resurfaced with no need to purchase additional parts.

Feel: Noticeably improved engine response and acceleration, we've weighed the stock ND flywheel in at 15.3lbs creating this easy to drive but laggy pedal response. This doesn't sacrifice much in the way of drivability but is a considerable loss in rotating mass.
