We run a single triangulated 4 link on our tube frame road race car , the lower links are triangulated only, they converge at the center of the diff housing at the bottom
and form a close to 90* , the top links are straight and parallel to the ground, this is called a "lotus link " style and has been used on MANY SCCA national championship GTL cars,It puts the roll center very low ( at the convergence point) it was built by Robbinson racing in GA. I have been thinking on trying it on a V8 car for a while using some 7075 link material, As far as coil-over location the stock location should work after reinforcement if you have good shock body clearance. The wider the mounting points from center of chassis the better. Dont over spring, you can calculate shock ratio based on location, See Accutune Off Road for some cool shock tech, off road mostly but the calculators they use to have are slick, real good suspension needs to be compliant and use its travel. Just some thoughts.
