Technical overview of the 3Racing SAK-D401 FRP chassis

The 3Racing SAK-D401 FRP Main Chassis provides a measured stiffness curve suited to racing setups for the Sakura D4 and D3 platforms. Its FRP laminate was selected to deliver repeatable deflection under load while maintaining fitment with existing mounting points.

Technical features and compatibility

  • Material: FRP layup chosen for consistent flex characteristics and resistance to fatigue over race cycles.
  • Compatibility: CNC-trimmed profile matches Sakura D4 and D3 hole patterns and component clearances for accurate installation.
  • Performance Boost: Promotes improved chassis predictability, aiding setup work such as roll centre, shock tuning and antiroll bar selection.

What setup changes are recommended after fitting the SAK-D401?

Begin with stock spring rates and adjust damper damping to match the firmer chassis feel; small increases in rear rebound or front droop can help rebalance handling.

Does the chassis affect weight distribution?

Weight change is minimal. Any balance shift is primarily due to altered stiffness and resulting dynamic load transfer, which should be tuned via suspension settings.

Are any reinforcements required for high downforce setups?

For aggressive aero or heavy accessory loads, consider targeted reinforcement around mounting areas or use complementary braces to maintain precise geometry under stress.
