3Racing SAK-A574 Racing Aluminium Wiper Arms Sakura Advance 21  [SAK-A574]

3Racing SAK-A574 Racing Wiper Arms Technical Overview

The 3Racing SAK-A574 aluminium wiper arms are engineered to firm up steering inputs on the Sakura Advance 21 chassis. With a 16.5mm dimension and aluminium construction, these arms reduce compliance in the steering linkage and provide a predictable pivot point for tuning foils and ackermann adjustments.

Performance Advantages for Tuning

Using aluminium minimises elastic deformation seen in stock components, improving steering fidelity and repeatability. That stability simplifies setup changes and helps accurately evaluate adjustments to suspension and steering geometry.

Precision Fitment and Installation Notes

SAK-A574 units are manufactured to match the Sakura Advance 21 mounting detail for direct replacement. Install using recommended torque settings and verify steering centre and linkage alignment before full-power testing.

Service Recommendations for Racers

As part of a race setup, inspect hardware torque after heat cycles and check ball link wear regularly. Integrating these arms into a balanced setup will aid consistent lap times and allow finer tuning of steering characteristics.
