Race Setup Focus for Steering Precision

The 3Racing CAC-138 Cactus 2WD Front Knuckle Axle is engineered to provide repeatable steering behaviour and robust operation under race conditions. Intended for tuners, it helps maintain consistent ackerman and more reliable roll centre behaviour when paired with standard Cactus 2WD suspension components. Use it as part of a setup sequence to reduce steering variability and simplify handling adjustments.

How does the CAC-138 affect steering geometry tuning?

This knuckle axle provides a stable mounting platform so small changes to toe and steering link positions produce predictable results, which is useful when dialling in corner entry and mid corner balance.

Are there setup recommendations for competitive use?

Pair the axle with a well-tuned servo and check steering centring under load. Fine adjustments to toe and caster can be used to tune turn-in aggressiveness without masking issues from worn steering parts.
