Race-Oriented Aluminium Front Upper Arms for Sakura D5

The 3Racing SAK-D5651 aluminium front upper arms are produced to give clearer steering feedback and repeatable geometry on Sakura D5 and D5S chassis. These parts help transfer setup changes directly into handling differences for faster iteration at the track.

Performance Tuning and Handling Consistency

By replacing compliant plastic arms with aluminium units, suspension kinematics become more stable under load. That stability improves predictability when adjusting camber, caster or roll centre for specific track layouts.

Practical Upgrades for Competitive Use

These arms support precise alignment work and make small tuning steps more measurable. They suit drivers who prioritise setup control and consistent lap-to-lap behaviour during practice and races.

What setup changes become more effective with these arms?

Camber and toe adjustments are more consistent, and changes to anti-squat or roll centre are easier to evaluate because the arms minimise unwanted flex.

Do these arms require additional geometry shims or spacers?

They fit standard mounting points but using small shims can help fine tune track width and camber behaviour depending on your setup targets.

Will aluminium affect component stress elsewhere?

Yes, reducing compliance at the arms moves some load to ball joints, pins and steering links. Inspect mating parts and upgrade bearings or pins if needed for competition use.

What is the recommended workshop check after fitting?

Verify pivot pin play, torque on fasteners and full steering sweep to ensure nothing binds. Log initial lap times and adjust damper settings to match the firmer arm behaviour.
