The 3RACING Sakura D3 CS SPORT Sakura Zero Low Friction Center Belt (SAK-D116) is a targeted upgrade for drivers refining drivetrain behaviour. Engineered to lower belt resistance, the SAK-D116 helps preserve momentum through gear trains and supports predictable power delivery under load.
Reducing friction improves the consistency of torque transfer and can make suspension and throttle tuning more repeatable. The SAK-D116 is well suited to drivers who adjust setup for handling and lap time improvements, without introducing complex modifications.
Install on a clean bench and ensure pulleys are parallel and belt tension is set to a neutral position that eliminates slack while avoiding excess preload on bearings. Verify alignment during test runs and inspect for glazing or edge wear that indicate replacement is needed.
