Introducing the pinnacle of Tamiya's touring car technology, the TRF421 4WD Touring Car Chassis Kit stands as the ultimate choice for R/C racing enthusiasts. Developed over two and a half years, this kit incorporates the latest advancements to ensure top-tier performance on the track. The TRF421 features an entirely new suspension and layout, promising enhanced speed, stability, and control for serious racers.
The TRF421 features a meticulously updated drivetrain that promises enhanced stability and performance. With a front direct coupling and a rear oil-filled gear differential, the equal-length front and rear drive belts minimize pitch, ensuring smooth and consistent power delivery. The motor's position, moved 22.7mm toward the chassis center, further stabilizes drivability, making this car a formidable contender on any track.
The TRF421 introduces a revolutionary suspension system designed for superior stability and adjustability. The rigid "A" design suspension arms are 7mm longer than those on the TRF420X, allowing for a stable roll and adjustable camber through the sliding upper arm mounts. Additionally, the three available damper pivot positions on the front and rear lower arms provide racers with a range of setup options to fine-tune their car's handling characteristics.
The new dampers on the TRF421 are 5.5mm shorter than those on its predecessor, reducing the chassis's weight and center of gravity for a more dynamic driving experience. Mounted directly to aluminum mounts, these dampers offer precise tuning capabilities using spacers. The new oil seals ensure maximum efficiency, making these dampers a crucial component for achieving optimal performance in high-downforce races.
