3Racing SAK-A534 Sakura Advance 2K18 EVO Brass Spacer Kit - Racing Setup Spec  [SAK-A534]

Technical spacer update for Sakura Advance 2K18 EVO setups

For competitive setters, the 3Racing SAK-A534 Brass Spacer is a measured component intended to refine chassis response. Designed for the Sakura Advance 2K18 EVO touring chassis, the M5 x 7 x 1.5 spacer offers repeatable stack height and predictable mass distribution for tuning experiments.

Tuning rationale for brass spacers

Brass provides definitive weight and rigidity compared with lighter alloys, enabling precise adjustments to roll centre and transient behaviour. Technically, using the SAK-A534 can help reduce lateral inertia and stabilise steering feedback during rapid direction changes.

Installation and setup workflow

Integrate the 3Racing spacer as a direct replacement in the spacer stack, then log baseline lap times and handling notes. Adjust one variable at a time and record changes to damping, camber and antiroll balance to quantify the spacer effect.
