Racing oriented 20 degree castor mount for Sakura D4

The 3Racing Sakura D4 20° Aluminum Castor Mount - SAK-D4817B/BK is a race-focused upgrade that tightens steering geometry and lowers chassis compliance at the front end. Manufactured with attention to fit and finish, the aluminium plate maintains alignment under lateral load and supports consistent suspension behaviour during drift entries and transitions.

How does this affect steering lock and turn-in speed?

Reducing flex at the castor pivot produces a firmer initial turn-in and more predictable lock progression, aiding drivers who tune steering ratio and ackermann for competitive entries.

What setup checks should be done after fitting?

Verify steering centring, toe settings and bump steer under full droop. Re-torque fasteners after the first sessions and confirm no binding at servo or bell crank linkages.

Can this part be combined with other tuning upgrades?

Yes, it pairs well with stiffer steering links, adjustable turnbuckles and hardened steering posts to create a coherent tuning package for precise drift control.
