[QUOTE="mac5005, post: 692270, member: 4650"] Get AS around 70%, make sure it doesn‚„t go above about 80% in droop. Shoot for upper links to be around 67-72% of lower link length, this will help the AS to not increase dramatically in droop. This is important so the rear doesn‚„t hop on big climbs. Next is to get pinion angle change less that 6 degrees total change. Get the AS in the front around 40% with no more than 15% increase in droop. Ideally get the roll axis angle as flat as possible, and the roll center heights as close as possible to the cam centerline, as close as practical. Also it‚„s better to have the rear roll center lower than the front, so if you are playing at speed and too fast into a curve, it pics a front tire up off the ground before the rear, this causes understeer. If the rear is higher than front and you blow throw a corner or curve, and it lifts the rear first you will have instant massive oversteer = bad. Try to get the shocks mounted with at least 6” - 7” of uptravel at ride height. You want the correct springs so that you have the springs preloaded 2”. If it takes more than 2” of preload to get your ride height, the springs are too soft. Less than 2” of preload and the springs are too stiff. Preload is how far the top nut is adjusted down compressing the springs, with the shock fully extended. At zero preload, the top nut would just touch the top of the spring with no free play, with shock fully extended. Again shoot for 2” of preload, so once the top nut touches the springs, keep threading downward to compress springs another 2”. [/QUOTE]
