I installed the Kyosho roll damper set and the carbon fiber plate (medium torsion) on my LM. NIGHT AND DAY DIFFERENCE! I am so happy. The rear is planted as expected.

These brushless motors are so powerful on the MR03VE, the rear requires these parts for me. This is a must have.
I am running a 10t pinion with 53t spur (64 pitch) 5.300 ratio on the factory motor mount.
