Tinkering with damper viscosity is a straightforward route to better handling. The Tamiya 54709 Silicone Oil 350 in 40ml format is suitable for all oil-filled dampers and allows careful adjustment of suspension response.
The 40ml bottle provides ample oil for repeated setup changes. Viscosities are colour-coded to make identification quick in a busy pit area and to cut down on accidental mixing of grades.
Higher viscosity values indicate a thicker fluid and a firmer suspension reaction, useful on smoother circuits to reduce body roll. Lower values give softer damping and better absorption over rough ground.
