The DragRace Concepts Slider 10" Bottom Plate is a great way to add some length to your DRC 8" Slider wheelie bar. By combining the arms (DRC-373 rear, DRC-375 mid) and bottom plate (DRC-374), and adding an additional cross brace (DRC-345), you can turn your 8" bar into a longer 10" option that will help to improve stability.
