Solid axles are now available as option parts for the Stage-D drift conversion kit. This new Solid Axle Set offers an extra tuning adjustment to help optimize the car for long drifts and extreme drift angles on various track surfaces. These axles can be used on the front and rear of the car for increased drift angle, or just on the rear for a realistic “maximum countersteer” look. These parts replace the internal diff gears of Nitro RS4 3 cars, and include all of the parts and instructions needed to convert one differential.
