Tamiya 15431 JR FRP Short Reinforcing Plate Set - Mini 4WD Chassis Stiffener  [15431]

Chassis stiffener plate - Tamiya 15431 JR FRP

The Tamiya 15431 JR FRP Reinforcing Plate Set provides a straightforward way for Mini 4WD builders to strengthen their cars. Made for MS and Super XX chassis layouts, the plates are intended to increase structural rigidity and help keep roller mounting angles consistent under load.

Design and fitment

These FRP plates are fitted between the centre unit and the front or rear sections of an MS chassis to add torsional stiffness where it matters. They can also be mounted to Super X side stays, giving racers the option to install mass dampers and better manage weight balance.

Benefits on the track

Keeping accurate roller angles helps reduce unwanted handling changes through corners and supports repeatable lap times. The Tamiya 15431 plates help maintain chassis geometry during higher speed runs, improving responsiveness and overall control on a variety of track types.
