    When you start messing with ride heights and get away from the manufacturer's recommendations, don't forget you will start moving roll centers around..As you start playing with lower and upper a arms angles, they will change dramatically...

        I know this is another way and more for helping with bump steer. If I remember right, a way to measure front ride heights is to have the right tie rod level and the left tie rod about 2 degrees up with the outside being higher.

          So if I set the right tie rod level and left tie rod 2 degrees up. Would I then measure to a flat spot on the front of the frame to get the ride height and then add an 1" to that measurement to figure out what I need to set my rear ride heights at?

            They don't really compare front to rear when measuring this way. Like I said measuring that way is more for helping with bump steer than actual ride heights. Once you have your ride heights set, check the angle on your tie rods and see where they are. If anything they will give you a secondary measurment for future reference. Just like measuring the angle of your a-arms as a secondary ride height.

              Oh ok gotcha. My problem really is trying to figure out what ride height to set the car out. I've read so many different heights, plus all of those are relative to tire size and where on the car you're measuring.

                Then measure a flat spot on the front of the frame and set the rake based on those heights?

                  Ride Height is a Generic term for each individual car. Like previously stated, set your Front lower arms where you want them, and your rear arms where you want them. Then Take your ride height measurements from some point on the frame. This will be your quick reference point on your chassis to come back to and check. I like the RF lower arm 1/4 in higher at the center of the lower ball joint than the center of the forward inner bushing through bolt on the front of the cross member. The Left side I like flat. The rears can be all over the place, just depends on how you have it jigged. But ride height should only mean something to your own car, not anyone else.

                    Ride height

                    If the left rear is higher than the right side it puts the upper bar at more of an angle than the right. With the angle on the upper being so much, when in body roll it can put MORE rear steer into the chassis. It will pull the upper mount forward.
                    You could go up 25# on the left rear spring. Go old school. Put a socket on the floor jack plate and jack rear end up in the middle. The right side should lift first. More it lifts before the left, more cross is on chassis.
                    You can try 53% on left. cross and rear, as a starting point. With the cross, simple thing to do is crank enough cross into it till it starts to push then back off till it feels good to you. Do a web search on what to do with the springs to fix certain parts of the corner. DON'T fiddle with shocks till you get the springs/setup sorted out.

                    Good luck, confusion can be a good thing.
