Benefits of the Tamiya 53156 Hard Inner Sponge

With higher rigidity than standard foam, this inner sponge helps maintain a consistent contact patch and reduces tyre squirm under load. That stability can translate to cleaner turns and steadier lap times for racers and club drivers alike.

Fitment and Quick Installation

This inner sponge fits a broad range of 1/10 on-road tyre designs and installs without major tyre surgery. Most hobbyists can fit the sponge with basic tools and a little patience, making it an easy performance tweak.
