Shift Weight Function: Mass Dampening and Settled Inertia
The Mazdaspeed3 and Mazdaspeed6 transfer more drivetrain vibration through the shift lever than comparable turbocharged platforms. The Cobb Shift Weight attaches to the factory shift lever mechanism below the shift boot, adding mass that dampens vibrations before they reach the driver’s hand.
Mazdaspeed3/6 Installation and Vibration Reduction
The shift weight installs at the factory shift mechanism using the provided hardware. The added mass also slightly reduces perceived shifting effort, consistent with the effect of a weighted shift knob.
