all that info is good but the shock angle will be a bit deferent for coil over springs leaf spring coil over shocks and strait axel like It1s10 said that is the way i like them. on the front if you look at some trucks or cars they are not tip in much the more you pull the in the angle the way i see it the more body roll you will have .but if the frame is narrow they will be at more angle to the shock so you want to make brackes to stand them off the frame and you do want the bottom of the shock as far to the end of the axel as you can get. this is a big deal on tub out cars and trucks if pull to much in at the top they are like a teeter-totter
