Track-ready Tamiya 54590 RC M-Chassis Super Hard Inner Sponge Set (4pcs) OP-1590  [54590]

Fine tune your M-Chassis with super hard inserts

For modelers wanting precise handling on speedy layouts, Tamiya offers the 54590 Super Hard Inner Sponge set. These inserts are tuned to give tyres added support when running at higher speeds or on hot surfaces.

Why choose super hard foam

Compared with the standard 60D Hard Inner Sponge set, the super hard foam increases carcass stiffness. That improved rigidity helps the tyre hold shape, translating to steadier steering and less unpredictable breakaway at pace.

Which tyres and what you get

The inserts fit a wide selection of M-Chassis tyres, including 50683, 50684, 51427, 53254, 53340 and 54216. Each pack contains four inserts so you can outfit all four tyres on your car in one go.
