The all-new, unique floating servo holder set includes graphite holder and aluminum bushings. The floating steering system is disconnected from the chassis and works fully independently without affecting flex. This makes the car easier to drive in high-traction conditions, and chassis roll is reduced especially driving through the curbs. The car also handles better on bumpy tracks. In combination with #302570 Steering Plate you can adjust 4 different flex characteristics. Using the graphite steering plate, chassis flex is medium; when using the steering plate with aluminum stand, flex becomes stiffer which results in more aggressive handling and increased steering. Thanks to the unique design of the servo holder, changing the flex of the steering system is quick & easy. There is no need for other parts, and there is no need to assemble/disassemble the servo holder. Adjusting the steering flex for a particular track is very quick & easy.
