The XRAY 303004 brass motor mount plate is a practical tuning part for the T4'18 chassis. Crafted from solid brass, it takes the place of the aluminium unit and adds approximately 4 g at the centreline to help even out weight distribution and reduce unwanted chassis flex for steadier on-track performance.
The plate features additional mounting holes positioned rearward on the chassis to shift ballast rearwards and increase rear traction. That layout helps deliver more predictable corner exits and easier throttle control on smooth surfaces.
