[QUOTE="fl-krawler, post: 547307, member: 884"] Take them with a grain of salt, because every driver, every rig, and every terrain will have a different setup that works best for them. These are my general rules when building susp. for customers and friends. Roll center height needs to be as high as humanly possible, and should be higher than the frame lower link mounting point lower links should be atleast 36" long, and minimum of 15 degrees of triangulation.. Also try to get them as flat as possible. I try to not let the frame end of the link mount be more than 2-3" higher than the axle end at ride height. The taller the upper link mount is on the axle, the more stable the rig will be and the better it will climb. Upper links separation from the lower links at the frame end should be between 70-85% of the separation at the axle end. Upper links should be around 85% of the length of the lowers Instant center (the imaginary point where the upper and lower links converge) should always be in front of the front axle.. never behind it.. Ideally in a perfect world you would want it right on top of the front axle. Antisquat: I've found numbers as low as 50% work better for going fast, to 100% for rigs that climb a lot of vertical ledges. Personally I like around 80-85% and the above rules get me pretty close to that number usually [/QUOTE]
