Refine Turbo Optima grip with Kyosho OTW131 Mold Inner Sponge

The Kyosho OTW131 Mold Inner Sponge is tailored to the Turbo Optima line, giving a snug internal profile that mirrors the tyre shape. Its firmer material helps tyres perform better on high-traction surfaces by stabilising the contact patch.

Optimised for high-traction tracks

Made for on-road racers who demand consistent grip, this inner sponge supports predictable tyre behaviour on smooth surfaces. The 50mm dimension is matched to Turbo Optima tyres for dependable lap-to-lap consistency.

Moulded insert for tyre stability

Precision moulding ensures the Kyosho OTW131 integrates with the tyre carcass to limit deformation during hard driving. The hard compound holds shape under pressure, helping with stability and steering accuracy.
