From McPappy Racing these ultra lightweight adjustable body posts are half the weight of their competitors. There is about four times the normal machining involved to allow for a very lightweight design. The elliptical design provides a varied exterior wall thickness to lighten the side walls and they even machined a large hole in the middle for extra weight reduction. There are two set screws instead of one which is nice in case you strip one out or want to come in from a different angle. The typical threaded hole in the bottom allows you to mount it traditionally to any flat surface like the chassis or bumper. There is also two threaded side holes which will allow you to mount to any perpendicular surface like a cross brace. This allows you to not only adjust the body post height up and down, but also side to side. The posts offer 0.40″ of height adjustability and the kit includes rough cut 3″ Delrin rods that you can cut to size. Available in anodized Beryllium orange or plain aluminium.
