Track-Ready Rear Insert Tamiya 53319 - Rear Inner Sponge Set for RC Boy's 4WD  [53319]

Rear tyre support for RC Boy's 4WD using Tamiya 53319 inserts

The Tamiya 53319 - Rear Inner Sponge Set is crafted to enhance the rear tyre behaviour of RC Boy's 4WD cars by reinforcing the tyre from the inside. These inserts sit inside the rear tyres to help keep the tyre profile consistent, which aids traction and rear stability during faster runs. The durable composition is suited to frequent track sessions and local club racing.

Practical gains from using inner sponges

Inner sponges are a straightforward tuning item that reduce tyre deformation and improve contact consistency. That translates into steadier acceleration and cornering feel on sealed tracks and hard-packed dirt circuits, making set up more predictable for weekend tuning.
