One can retain stock height by LOWERING the MII crosmember. This only works with the kit designed to use coil over shocks. It takes 3" to 3.5" spacers on the underside of the frame to regain factory height. This brings other variables into the equation ranging from little change with an all aluminum LS to big changes with a cast iron six. The raised chassis results in increased body roll so heavier springs and shocks come into play. We have a whiz bang techie that can lay it all out on a computer, even to the point of reaction on different road surfaces and corner reaction. The MII shown is a Heidt's but we now use mostly Fatman units.
