3Racing FW05-RR009 Competition Main Chassis 4mm for Kyosho V One SII  [FW05-RR009]

Competition-Oriented 3Racing FW05-RR009 Chassis

The 3Racing FW05-RR009 4mm aluminium main chassis provides a stiffer core platform for the Kyosho V One SII, helping drivers extract more consistent handling from fine-tuned setups. The 4mm thickness delivers measurable reductions in torsional deflection while maintaining a practical mass for race applications.

Engineering Notes on Aluminium Performance

Aluminium offers predictable stiffness characteristics that make setup changes more effective. The 3Racing FW05-RR009 follows Kyosho V One SII mounting locations to ensure alignment with existing suspension geometry, allowing precise adjustments to spring rates, roll centre and damper tuning without geometry compromise.

Race Setup and Tuning Benefits

For competitive users, this main plate improves feedback under braking and turn-in, enabling clearer tuning decisions. The increased chassis rigidity can also stabilise tyre load distribution, helping to reproduce lap-to-lap behaviour during qualifying and race runs.

The 3Racing FW05-RR009 is a pragmatic performance upgrade aimed at drivers who demand repeatable handling and a stable baseline for setup changes on the Kyosho V One SII.
