Tamiya 54590 RC M-Chassis Super Hard Inner Sponge Set (4pcs) OP-1590 - Race grade inserts  [54590]

Tune M-Chassis handling with super hard inner sponges

For competitive RC enthusiasts looking to tighten front-end response, Tamiya introduces the 54590 Super Hard Inner Sponge set. These inserts are intended to boost tyre stability when running fast or on warm track surfaces.

Performance-focused foam

The super hard inner sponges are stiffer than the stock 60D Hard Inner Sponge set, providing improved carcass support. That added stiffness helps to keep tyre shape during high-speed sections, aiding vehicle predictability.

Compatibility and kit details

The sponges are compatible with many M-Chassis tyres, including part numbers 50683, 50684, 51427, 53254, 53340 and 54216. Each pack supplies inserts for four tyres so you can fit all corners without buying extra parts.
