The Tamiya 42382 TRF420X Touring Car Chassis Kit builds on Tamiya's TRF lineage with a belt-driven 4WD layout in a 1/10 scale package. Its double-deck frame is engineered to deliver controlled chassis flex for improved traction and predictable handling on paved circuits.
Chassis rigidity can be tuned by changing upper deck screw positions, allowing drivers to match flex to their style or track grip. The TRF420X keeps the motor location from the TRF420 while moving the spur gear ahead of the motor to reduce pitching under acceleration and improve straight-line stability.
Owners can swap between a 2.25mm carbon fiber lower deck or a 2mm aluminum lower deck to suit different surfaces. The suspension uses the TRF420 platform with dedicated bulkheads for accurate assembly, and new 43mm lightweight rear drive shafts help sharpen response.
The Tamiya 42382 TRF420X is a versatile competition-ready chassis kit that rewards careful setup and tuning. Its combination of adjustable stiffness and quality components makes it a strong choice for racers wanting a nimble, dialable platform.
