The Tekno RC 30g Brass Balance Weight allows you to fine-tune the balance of the NB48 2.0 and enhance steering. Designed to fit under the steering bell cranks, the CNC machined weight mounts directly to the chassis using an 3x10 flat head screw (TKR1323). There is room for one weight so you can choose the 15g or 30g variant depending on your preferences and track conditions.
