Detailed 1/12 Tamiya 58509 Toyota Tom's 84C on the RM-01 Platform

For scale modellers and racers, the Tamiya 58509 Toyota Tom's 84C on an RM-01 chassis offers both historical styling and a contemporary, adjustable running gear. The kit mirrors the iconic 1985 racer while providing a Direct Drive 2WD system and an advanced PBLR suspension for predictable track manners.

What Makes the RM-01 Stand Out

The RM-01 chassis targets the renewed interest in 1/12 competition, delivering a Direct Drive 2WD configuration for efficient delivery of power and a Pivot-Ball Link Rear arrangement for consistent handling. A 2.5mm FRP lower deck improves stiffness and the resin gear case supports height adjustments. While the kit includes a type 380 motor, the motor plate can be removed to fit a 540 motor for higher speed applications.

Suspension Design and Tuning

The PBLR arrangement combines a centre pivot ball with pitch and roll dampers plus side links to let you fine tune pitch and roll balance. Fit roll springs for more advanced setups, and the aluminium differential housing makes it simple to access and tune the ball differential without removing wheels.

Scale Finish and Battery Options

The polycarbonate body reproduces the Toyota Tom's 84C livery and comes with stickers and a driver torso for added realism. Battery mounting accepts square packs secured with glass tape, and the Tamiya LF Battery LF1100-6.6V Racing Pack is a solid recommendation for reliable power delivery during sessions.
