Yokomo RP-056A Racing Performer Rotor #56 M3 D12.5xd5.00  [RP-056A]

This really is an optional rotor for rushing Performer M3 series engines which allows you to definitely adjust the energy feeling based on competition laws. With a magnet external diameter of 12.5mm and inner diameter of 5.00mm, it uses a high-power magnet that achieves overwhelming acceleration and top speed, providing you an advantage in events.
even though the magnetic force is lost as a result of high temperatures, you'll refresh the engine power by changing the rotor! It is possible to regain your initial power and feeling.
