Motor Mount Rigidity Upgrade for Race Setups

For competitive setups the CAC-128 stiffener reduces compliance at the motor mount interface to preserve gear alignment under high torque. The part delivers a firmer mounting plane which helps maintain consistent mesh and predictable power transfer during aggressive throttle application. Fitment is direct to the 3Racing Cactus 2WD motor mounting points and integrates with common tuning parts without altering motor position.

How does the stiffener affect gear mesh stability?

By constraining mount movement the stiffener keeps pinion and spur alignment more consistent during acceleration spikes, reducing transient mesh variation that can cause noise and wear.

Is there a recommended torque spec for the mounting bolts?

Use the manufacturer recommended torque for motor mount fasteners and recheck after initial runs; avoiding over-torque preserves threads and ensures the stiffener seats correctly.

Will the stiffener work with upgraded drivetrain components?

Yes, the CAC-128 is compatible with common upgrade motors and gears so long as the upgrade respects the stock mounting footprint and clearance dimensions.
