Tamiya M07 Racing front lower suspension mount 5 degree caster M07-18 by 3Racing  [M07-18]

Technical summary for tuners

This front lower suspension mount is a dedicated hop-up for the Tamiya M07 chassis that introduces a 5 degree caster bias to alter front geometry. It replaces the OEM lower link mount and is intended for competitive setup work where precise changes to steering axis and roll behaviour are required.

In practice, the 5 degree caster moves the steering pivot to improve initial turn-in and longitudinal stability. The component is designed for racers who want finer front feel and predictable self-centering without replacing major suspension architecture. Handling changes come from geometry only and do not involve powertrain or braking modifications.

Installation follows standard M07 front assembly procedures: remove the factory lower mount, fit the hop-up in the same position and torque hardware to spec. After installation, confirm wheel alignment and steering travel, then perform controlled test laps while logging changes to corner entry and mid-corner balance.

Service checks should focus on fastener torque and wear at mounting points after initial running, and on steering linkage free play since caster adjustments can modify linkage geometry and binding potential.
