The 3Racing SAK-A578 Graphite Upper Deck increases the centre stiffness of the Sakura Advance 21 without adding bulk. Its graphite construction supports consistent handling characteristics during race and practice sessions.
Graphite offers a desirable stiffness to mass ratio that limits unwanted flex while keeping the car agile. Installing this upper deck promotes steadier turn in and more predictable mid corner balance.
Mounting the 3Racing SAK-A578 to the Sakura Advance 21 follows stock mounting locations. Tighten fixings evenly, run a short test session, and then recheck hardware to ensure no movement has developed.
