The 3Racing SAK-A574 aluminium wiper arms are made to improve steering stability on the Sakura Advance 21. At 16.5mm and crafted from aluminium, they reduce flex and give more predictable steering inputs for competitive weekend running.
Aluminium parts cut down on deflection and part wear, producing crisper responses at the wheel. That steadier behaviour helps drivers maintain consistent lines and braking points across a session.
SAK-A574 installs directly to the Sakura Advance 21 mounting points. The swap is straightforward; follow standard procedure to secure linkages and recheck alignment after the first outing.
As a durable upgrade, these wiper arms benefit from periodic inspection of screws and ball joints. Correct torque and routine checks will keep steering behaviour reliable lap after lap.
