Track-Proven Support with Tamiya 40142 Rear Inner Sponge

The Tamiya 40142 Rear Inner Sponge provides dependable tyre support for 1/12 scale on-road RC cars. This precision foam insert helps the tyre keep its shape under braking and cornering loads, resulting in steadier steering response and more consistent lap times on paved and carpet surfaces.

Performance Highlights for Tamiya 40142

Optimized Support: Close-fitting foam that stabilizes tyre sidewalls for improved contact with the track.
Durable Material: Resilient foam built to retain shape through repeated runs and hard acceleration.
Compatibility: Manufactured to fit 1/12 on-road wheels for a straightforward swap.

How will the sponge affect my lap consistency?

By keeping the tyre profile stable under load, the insert reduces unpredictable grip changes so your steering feel and lap times stay more consistent across runs.

Can I trim this sponge to suit different wheels?

Minor trimming is possible to fine tune fit, but cut sparingly and test fit on the tyre to avoid compromising support.

Is this insert suitable for both rubber and foam tyres?

It is optimised for standard on-road rubber tyres and delivers best results with soft to medium compounds.
