Race-Ready Wheel Support with Tamiya 40142 Rear Inner Sponge

The Tamiya 40142 Rear Inner Sponge is aimed at 1/12 on-road racers who need repeatable handling. This foam insert keeps the tyre shape under corner loads, giving crisper turn-in and more consistent exit traction across multiple runs.

Key Benefits of Tamiya 40142

Stability Boost: Snug internal fit reduces tyre deformation for steadier grip.
Robust Foam: Material chosen to handle frequent use without losing form.
Direct Compatibility: Suits standard 1/12 on-road wheels for easy replacement.

Will this insert change steering feel on high grip tracks?

On high-grip surfaces the insert helps keep tyre shape which can make steering more precise; you may need minor trim or setup tweaks to dial balance.

Can it be used with foam-backed tyres?

It is optimised for standard rubber tyres; compatibility with foam-backed types varies so check fit and feel before racing.

How often should I replace the sponge?

Replacement depends on usage, but inspect regularly and swap out if the foam shows compression or tearing after heavy track time.
