Xray XII Front aluminum active brace
New from Xray for their 1/12th scale pan car chassis, the XII, is this front aluminum active brace. Mounted between the front blocks, the brace prevents tweak as the result of a crash but it also can be used to setup the car. Assembled in 2 different versions, with rubber o-rings or with an aluminium roller, the former makes the brace softer and so increases front traction and steering, while the latter assembly stiffens the front and so decreases steering.
