The Tamiya TRF421X RC On-Road Chassis represents the peak of touring car engineering, designed specifically for those who demand the highest level of performance on the track. This 2-belt 4WD racing powerhouse builds on extensive race data to provide a platform that handles high-traction surfaces with incredible precision. With a revised layout that lowers the motor position and optimises weight distribution, every lap feels more composed and predictable even as speeds increase.

Finding the perfect setup is a breeze because this kit offers a wide range of tuning options, including adjustable knuckle arms and precision stabilisers. The combination of an aluminium lower deck and carbon upper deck creates the ideal balance of chassis flex and rigidity for competitive racing. This chassis is the real deal for anyone looking to push their driving skills to the absolute limit because it is built to handle the heat of top-tier competition.
