Tamiya 15431 JR FRP Short Reinforcing Plate Set - Compact Mini 4WD Upgrade  [15431]

Short FRP reinforcing plates by Tamiya 15431

The Tamiya 15431 JR FRP Reinforcing Plate Set is aimed at hobbyists wanting a simple reinforcement option for Mini 4WD. Compatible with MS and Super XX chassis, these plates reduce chassis flex and support consistent component alignment.

Compatibility and mounting

Install the plates between the centre and either the front or rear modules on MS chassis to add stiffness where the chassis tends to twist. For Super X builds, mounting on the side stays allows space for mass dampers and alternate weight setups.

Performance implications

Less chassis flex means more predictable cornering and steadier handling at speed. The Tamiya 15431 plates help keep roller attachment points stable, which supports consistent corner entry and exit behaviour across multiple laps.
