The 3Racing Sakura D4 Aluminum Upper Deck Mount (SAK-D405) is engineered to raise chassis stiffness for drivers who tune for lap time consistency. Manufactured to tight tolerances for the Sakura D4 platform, this aluminium deck mount offers a stable mounting plane that aids repeatable suspension geometry and predictable weight transfer.
Fitting the SAK-D405 increases torsional rigidity, improving the vehicle's response to roll and pitch inputs. This makes shock and anti-roll tuning more effective and reduces setup drift across runs, helping teams maintain consistent balance on different track surfaces.
Install the 3Racing Aluminum Upper Deck Mount with controlled torque on all fixings and confirm alignment to chassis datum points. For competitive use, re-check fastener torque after break-in laps and include the mount in routine setup inspections to preserve tight tolerances.
