Race-Grade Body Mounts for Sakura D4

The 3Racing Sakura D4 Aluminium Body Post Steel Ball Stud Set, model 3RAC-BS4804S, provides a precise, low-tolerance upgrade to stock body mounts. Machined aluminium posts combined with hardened steel ball studs reduce flex at the mount points to maintain body alignment under dynamic loads typical in competitive running.

Tuning Benefits and Track Performance

Upgrading to aluminium posts improves repeatability when setting body height and mounting positions, which matters for aerodynamic balance and bump steer on track. The secure fit of the steel ball studs minimises play, translating into more consistent front-end response during corner entry and mid-corner adjustments.

Fitting Notes for Setup-minded Drivers

Designed for Sakura D4 chassis patterns, the ten-piece kit installs using standard fasteners and allows fine tuning of shell height via shims or washers. Inspect post alignment and confirm equal body post heights to keep suspension geometry predictable after the upgrade.

How do aluminium posts affect handling consistency?

Aluminium reduces mount deformation, so body position is more repeatable lap to lap, improving feedback for precise setup changes.

Should I use shims to tune ride height after fitting?

Yes, use thin shims or washers to achieve exact shell height and balance; consistent heights front to rear help maintain predictable aero and suspension behaviour.

Any track maintenance tips for these parts?

Regularly check stud tightness and clean debris from the post interfaces between sessions. Re-torque fasteners and replace any studs that show thread damage.
