The 3Racing SAK-XS306/FRP rear shock tower increases rear height by 4mm on Sakura XI KIT-XS/NU cars to help stabilise the chassis during cornering. This compact upgrade is aimed at hobbyists who want a quick, measurable change to their suspension geometry.
The extra 4mm reduces chassis roll and improves shock travel consistency, which can be especially apparent on fast sweepers and bumpy exits. It helps maintain composure when accelerating out of corners.
Built for direct compatibility with the Sakura XI KIT-XS/NU, the SAK-XS306/FRP installs with standard hardware. It is easy to swap in for on-the-spot testing between runs to compare handling differences.
