I have a 3 linc with 17 inch arm on left and 20 inch on right my coil overs and shocks are mounted 3 and a half inches below the axle center line and my lincs mount 2 inches below them .....I was looking through an old steve smith book and it said the best location for the springs and shocks is 7 inches below the axle centerline ...now I am wondering if I should redo my brackets so they are 7 inches below ......springs in front shocks in back .....any advise is appreciated .

I would like to know the answer to this as well, new to 2 (or 3) link setup.
Any advice as to the best publication to go to learn the in's and out's of this type of rear suspension would be appreciated.
Curious about link lengths and angles relative to each other as well as what different spring mounting locations will do for the handling of t he car.
Thanks in advance!

The springs are about 11/2 below the axle tube and about 4 inches in front ,the shock is about 4 11/2 behind on both sides,I have a spring bucket on the right side on top of the rear end mounted to the rear of the tube ....when the track goes dry I am planning on taking the C.O.E off the front and running the right rear on top of the housing with a screw jack.....does this all sound O.K.?

moving the RR behind on the 3 link will tighten the car up getting in then helps allow the car to roll over.

"have a 3 linc with 17 inch arm on left and 20 inch on right my coil overs and shocks are mounted 3 and a half inches below the axle center line and my lincs mount 2 inches below them"

are your links are mounted 2 inches BELOW the 3 1/2 inch mark where your springs/shocks are mounted? Am I reading that right? or are your link mounts 2 inches below axle centerline? If your links are mounted 5 1/2 inches below the axle they probably need raised up. On our dirtworks the trailing arm was 5 1/2" below axle centerline with the springs/shocks 8 inches below axle centerline. We moved the trailing arm holes UP 1 1/2 inches and forward about 1/2 inch. Moving them up and forward makes the car react quicker, getting it up on the bars

O.K....I just measured evrything and here is what I actualy have...links are 2 3/4 directly bellow the housing C.O.E 1 1/4 below housing and 3 1/4 in front with the bottom of the spring about level with the top of the housing (I have spacers between the bottom heim and lower spring plate to clear lower linc ).....I am coming from a mono leaf car to this one and the spring concepts seem the same to me but there is a **** of alot more articulation in this car,roll stear etc....so this steeve smith book got me thinking I better start asking some qustions to make sure my set up would work.....I appreciate your input.
