The X4 top deck features milled holes for unique tweak-free top deck screws and works with the center layshaft location in the middle of the chassis. Machined from 2.0mm graphite material, the shape of top deck is specifically designed to obtain maximum traction and great steering faculties at precisely the same time. The unique top deck flex settings enables easy adjustment of this flex between 4 different traits. The utmost effective deck can be attached to the engine mount using these alternatives: 1.) smooth setting - No bushing or bearing can be used. This permits maximum flex and maximum steering. But the automobile is less stable on-power. 2.) Soft-medium setting - The top deck is attached to the motor mount via ball bearing. This setting eliminates some steering but improves stability. 3.) moderate setting - the most effective deck is connected to the engine mount via special screw M3x5.5mm behind layshaft. This environment eliminates a little bit of steering but improves stability. 4.) Stiff setting - the very best deck is connected to the engine mount via unique screws M3x5.5mm behind plus in front side of layshaft. This environment provides maximum stability and in addition improves steering response.
