The thin-leg stator offers another benefit - weight reduction. By reducing the motor's weight, handling and chassis turning flexibility improves. Machined parts such as the can, timing cap, back plate, and sensor assembly have been placed on a diet. An entire section of the front plate has been removed to reduce weight with an added benefit of allowing the user to re-position it to lower CG depending on which type of car it is being installed in. A savings of nearly 30g has been achieved! Additionally, the motor's length has been reduced by more than 2mm, which aids left and right balance and moves mass towards the center of the chassis.
An all-new high-strength, balanced rotor is more powerful that it's predecessor. Because the rotor is interchangeable with those in 540-M3 spec motors, a wide range of tuning options are already available. Precision stainless steel ball bearings have been fitted to accommodate high RPM loads with exceptional efficiency and reliability.
