Racing-Focused Front Wheel for Cactus

The 3Racing CAC-121 is engineered to reproduce precise Kyosho Cactus 2WD front geometry, aiding setup repeatability and consistent tyre behaviour. Its design supports quick swap tests during practice and helps drivers isolate changes to tyre and steering settings.

What suspension settings pair well with this wheel?

Start with neutral caster and a medium front roll centre; use the 3Racing CAC-121 to evaluate tyre compound and front spring rate changes without rim geometry variables.

How does rim stiffness affect handling here?

Rim stiffness influences contact patch feedback; the CAC-121 balances rigidity and compliance so that tuning tyres and toe yields predictable results on corner entry.

Recommended process for on-track testing?

Change one variable at a time, fit the 3Racing CAC-121, record lap times and steering feel, then adjust tyre compound or toe to assess the influence of each change accurately.
