Race-Focused Rear Geometry for 3Racing Cactus 2WD

The 3Racing CAC-306 is a machined aluminium rear suspension mount developed for mid-motor Cactus 2WD layouts. The specified 3.5-degree angle shifts rear traction characteristics to improve rotation and corner exit consistency, aiding precise setup adjustments during race preparation.

Technical Benefits of an Aluminium Rear Mount

Aluminium provides predictable stiffness under load, reducing compliance that can mask tuning changes. The CAC-306 produces repeatable feedback for suspension tuning, helping drivers dial in roll centre and balance with fewer variables.

Integration and Setup Considerations

Designed to bolt in to the original 3Racing Cactus 2WD mounting points, this mount maintains compatibility with standard arms and hardware. After installation, adjust toe, camber and diff settings to optimise the new rear behaviour for your track conditions.

How does the CAC-306 influence tuning strategy?

The 3.5-degree rear bias generally increases traction and rotation, so expect to revisit anti-squat and diff settings to find optimal mid-corner balance.

Is heat treatment or additional machining required?

No additional machining is needed. The part is ready to fit; verify fastener torque and inspect for interference before track testing.

What setup checks are recommended after fitment?

Perform a baseline lap, then refine toe, camber and diff settings. Monitor rear traction through progressive throttle application to confirm desired behaviour.
