Xray XB4 brass rear chassis brace weight
Coming from Xray is a 40g brass rear chassis brace weight for the XB4 1/10th scale 4WD buggy. The optional brace fits in the lower part of the composite brace, connecting directly to the chassis and generating more stability while replacing the original composite brace insert. The weight of the car is moved more to the rear, improving in-corner rotation and lowering the centre of gravity.
