Awesomatix have released a new spur gear damper system for all A700 cars. The new system has damping from the o-rings which softens the reaction from the motor and makes the shaft transmission more similar to belt transmission when the throttle or the brake are applied. Lap times become more consistent and the car is easy to drive. In order to install this system you should increase the two current holes on the spur gear to 5mm. Awesomatix plans to produce its own line of spur gears with these holes in the future.
