Precision Rear Tower for Setup Tuning

The 3Racing SAK-XS306/FRP rear shock tower provides a controlled 4mm increase to the Sakura XI rear mounting plane, allowing targeted changes to roll centre and shock leverage on KIT-XS/NU chassis. This part is intended for racers and tuners who iterate shock travel and damping to extract consistent lap times.

Competitive Handling and Tuning

Raising the rear tower by 4mm alters leverage ratios and can reduce lateral roll under load, improving mid-corner stability. Use this tower in combination with measured changes to shock oil weight and spring rates to maintain a balanced front to rear transition.

Compatibility and Serviceability

Designed for direct fitment on Sakura XI KIT-XS/NU models, the SAK-XS306/FRP integrates with stock mounting points for quick installation. Check screw torque and alignment during service intervals to preserve consistent geometry and repeatable setup data.

How does the 4mm change affect shock pivot angles?

The added height slightly increases the effective shock angle relative to the chassis, which can change damping leverage; compensate with damping adjustments rather than large spring changes.

Should I update my setup sheet after fitting?

Yes, record shock lengths, spring free lengths and preload, plus any oil weight changes so you can compare lap telemetry or driver feedback across runs.

Is there a recommended shock oil range to start with?

Begin with your baseline oil weight and test one increment lighter or heavier depending on whether you need quicker response or more bottoming resistance, then refine from there.
