Xray T4’21 brass chassis T-brace
From Xray is this new T4’21 brass chassis T-brace that makes the car more stable, generates more rear traction and allows chassis flex adjustments to alter steering characteristics by adding and removing screws from the brace. Adding 10g additional weight the T-brace can be connected to the motor mount to create an even stronger centre structure which makes the car more stable and easier to drive while pushing the pace even faster.
