Technical Upgrade Notes for Sakura D5

The 3Racing SAK-D553/GR graphite upper deck is manufactured to enhance the torsional characteristics of the Sakura D5 chassis. Using well graded graphite, the deck increases upper section rigidity to reduce unwanted deflection between suspension pick points. This clear change in stiffness lets experienced tuners refine roll centre and transient response without significant weight penalty.

Racing Setup Advantages

Integrating the 3Racing SAK-D553/GR into a competitive setup provides a more stable platform for shock and antiroll adjustments. A firmer upper deck sharpens steering feedback and allows finer incremental changes to damping and antiroll tuning, helping optimise tyre contact patches during lateral load shifts.

Specifications

  • Material: Graphite
  • Compatibility: Sakura D5 Chassis

How does the deck affect tuning sensitivity?

A stiffer upper deck reduces baseline chassis flex, which increases sensitivity to small changes in damper settings and antiroll bar adjustments. Expect finer tuning steps when dialling in balance.

Any recommended assembly notes for racers?

Use the original mounting locations and torque screws evenly. Check for burrs on mating surfaces and use medium strength threadlocker on track cars to prevent loosening.

What should I consider when switching from stock deck?

Expect a firmer feel and altered load transfer. Revisit shock oil weight and spring rates to match the increased chassis stiffness, and log lap times to confirm desired handling gains.
