Improve chassis rigidity with the 3Racing SAK-A578

Fitting the 3Racing SAK-A578 Graphite Upper Deck to a Sakura Advance 21 increases the centre section rigidity without a weight penalty. The durable graphite build helps maintain consistent behaviour under race and practice loads.

Why graphite helps handling

Graphite provides a clean strength to mass ratio that reduces unwanted flex while keeping the car nimble. Installing this upper deck can help the Sakura Advance 21 track more predictably at speed.

Installation and care guidance

The SAK-A578 installs directly to the Sakura Advance 21 chassis using existing mounting points. Tighten hardware progressively, recheck after the first runs, and inspect for any stress at screw holes to ensure longevity.
