The Tamiya 19604 Knuckle-Breaker is a 1/32 scale assembly kit that reflects performance-minded Mini 4WD design. Mounted on the Super X chassis, the semi-monocoque construction enables motor removal from underneath, so you can change or service the motor without removing the body shell.
It rides on 24mm diameter and 9mm width slick tyres to prioritise speed and stability on straights. The body includes vertical fins running from the cockpit to the tail to refine airflow and support steady handling. Two gear choices are provided, 3.5:1 and 4:1, allowing builders to tailor the car for acceleration or higher top speed.
Plenty of Grade-Up Parts are available for tuning and personalisation. The Knuckle-Breaker suits hobby racers and collectors who want a versatile kit that responds well to setup changes.
