3Racing Sakura D4 Rear Bulkhead Cover - 3Racing SAK-D4811/BK Aluminium Edition  [SAK-D4811/BK]

Improve Rear Rigidity on the Sakura D4 with an Aluminium Cover

The 3Racing Sakura D4 Aluminium Rear Bulkhead Cover provides a stiffer mounting point for the rear end of the Sakura D4 chassis. Fabricated from machined aluminium, it reduces flex under load and contributes to steadier handling and a more predictable rear feel during spirited driving.

Performance Reasons to Fit Aluminium Parts

Aluminium offers better dimensional stability than plastic in demanding conditions. Replacing the stock rear bulkhead with this 3Racing aluminium cover helps maintain alignment and steering consistency, which is useful for drivers chasing repeatable lap times.

Installation Notes and Best Practice

When fitting the 3Racing Aluminium Rear Bulkhead Cover, tighten fixings evenly and check torque after the first few runs. Inspect the part and screws regularly, especially after impacts, to ensure ongoing correct operation. It fits alongside standard Sakura D4 upgrade parts.
