Chassis stiffness and setup control for 3Racing SAK-F72 - FFEX

The 3Racing SAK-F72 - FFEX graphite main chassis provides a markedly firmer structural backbone for KIT-FFEX platforms. Its graphite construction reduces torsional deflection, improving repeatable handling characteristics that are essential when refining suspension and steering geometry.

Material and handling considerations

Graphite offers a favourable stiffness to mass ratio, enabling reduced platform flex without adding significant weight. The SAK-F72 - FFEX plate aids quicker steering feedback and more consistent load transfer, which helps when testing incremental setup changes on track.

Compatibility, installation and tuning notes

Manufactured to match KIT-FFEX mounting points, this chassis is intended as a direct replacement. After installation, expect to revisit shock valving, anti-roll balance and toe settings to capitalise on the improved rigidity.

Specifications

  • Material: Graphite
  • Compatibility: KIT-FFEX
  • Weight Reduction: Enhanced for better performance

As a technical upgrade, the 3Racing SAK-F72 - FFEX chassis is suited to competitors and tuners who require a stable base for precise setup work and consistent lap performance.

What setup areas should I adjust after fitting the chassis?

Reassess shock spring rates and damping, anti-roll bar stiffness and toe settings. The stiffer platform often needs softer dampers initially to maintain compliance.

How does graphite affect chassis flex tuning?

Graphite reduces unwanted flex, narrowing the tuning window for flex-related adjustments. That makes other setup variables like camber and roll centre more influential.

Any torque recommendations for fasteners?

Use manufacturer-recommended torque for aluminium and plastic interfaces. Avoid over-tightening into graphite to prevent edge cracking; check hardware after first few runs.
