The 3Racing M05-07/WO Graphite Rear Suspension Pin Stiffener is a focused upgrade for Tamiya M05 racers seeking crisper rear-end behavior. It increases lateral and torsional stiffness at the rear pin junction to reduce transient flex under load.
Using graphite allows targeted stiffness without a significant mass penalty; this helps maintain front-end sensitivity while improving rear stability. When fitting, assess rear roll and adjust damping or spring rates to exploit the stiffer rear platform effectively.
Install the 3Racing M05-07/WO into the stock rear pin locations of the Tamiya M05, securing all fasteners to the recommended chassis torque. Verify geometry after fitting and perform iterative test laps to dial in shock valving and toe settings for optimal balance.
