The Tamiya 49272 SSG Carbon Fiber Upper Deck is designed to reduce unwanted flex on the TRF414 chassis while keeping overall weight down. Made from grey carbon fiber, it strengthens the centre section and helps the car maintain consistent traction through a range of track surfaces.
Carbon fiber delivers a higher stiffness per gram than many stock materials, so swapping to this upper deck gives a more direct steering feel and improved feedback without a big weight penalty. It is a common upgrade among drivers chasing repeatable handling.
Install the 49272 upper deck by following the chassis mounting pattern and secure all fasteners evenly. Check that the deck sits flush and recheck screw torque after the first few runs to maintain structural integrity.
