Tamiya M-07 Precision Rear Suspension Arms - JR-M705-LB by Jazrider  [JR-M705-LB]

Stiffer rear arms for controlled geometry

The JR-M705-LB aluminium rear arm is a precision replacement component made for the Tamiya M-07 chassis. It substitutes the stock arm with a machined aluminium piece to give firmer mounting for rear linkages and to preserve alignment under more demanding driving conditions.

Compatibility is confined to the M-07 platform as indicated by the product name. Installation follows the familiar process for M-07 arm removal and refit and uses the car's existing mounting pins and hardware. Standard hex tools are adequate; confirm clearance before final tightening.

In tuning practice, these arms lower flex at the arm pivot, which tends to stabilise changes in rear toe and camber gain and helps you dial in consistent lap times during setup work.
