Tamiya 54590 RC M-Chassis Super Hard Inner Sponge Set (4pcs) OP-1590 - High speed tyre tuning  [54590]

M-Chassis tuning with super hard inner sponges

For serious RC hobbyists aiming to refine handling on fast tracks, Tamiya presents the 54590 Super Hard Inner Sponge set. These inserts are made to increase tyre stability and consistency when speeds climb or conditions heat up.

Built to enhance track control

The super hard inner sponges offer a step up from the standard 60D Hard Inner Sponge set by delivering greater rigidity. That extra firmness helps maintain predictable steering and reduces tyre deformation during sustained high-speed runs.

Fitment and pack contents

These inserts suit a broad range of M-Chassis models and are compatible with tyres such as 50683, 50684, 51427, 53254, 53340, and 54216. Each pack contains enough inserts for four tyres, so you can equip all four corners of your car.
