I'm hoping to get some feedback on ride height for each corner and would one of the more experienced wrench's tell me if there is a limit to how far the jacking bolts should be allowed to protrude out of the bottom of the front leaf spring to where they hit on the control arm.

For the sake of keeping information realtive and meaningful, I am measuring from a level floor vertical right through the center of the wheel to the bottom of the wheel well lip.

LF...27" RF...26 1/4"

LR...28 3/8" RR...28"

Would look at a couple things. First check your shocks to make sure their not leaking? Check the composition of the " spring plate" probably not right name anyway check to make sure it isn't freying or delaminating of any kind. Your adjustment bolts should relatively be at the same adjustment left to right not front to back. Also check to see if they are ripped from the actual metal or cracked. I don't have any factory spec on the actual ride heights but you could measure one or just use preference. Good luck!:patriot:
 
No apparent shock or mounting issues but the maximum raise I can get out of the bolts still leaves my car slammed in the front, I have pretty much determined that it has had a lowering front spring installed, that i will be taking out or dealing with the ride height in other ways but it has to come up and inch in the front the next time I can work on it, it is plenty drivable but does not suit me.

Did you ever call D3 and ask them if they had worked on your car?
 
No, I did not as I was thinking they were out west and mine was always in south florida until my purchase which made it seem unlikely but worthy of checking now that I feel I am dealing with a spring change.
 
The manual calls for a special tool to adjust the front spring adjuster bolts. It says you will damage the rubber shear pad on the end of the bolt without it. PN J 42743
Mine is 27-5/8 RF 27-3/4 LF at the wheel wells.
 
I can see that if it was needed to unload the front spring but in my case I lifted the car to remove the suspension load and then used a floor jack to lift the spring off the control arm and the jacking bolt rubber pad just begin to touch as I ran out of useable adjustment.

I wish either I had the ability to lift and look at another car or someone could post a picture of their spring, that I could compare to be certain what I am dealing with. Otherwise I am guessing the answer is obvious that I am dealing with a lowering spring otherwise it could not be this low with the adjustment maxed out in the direction of lifting and it is still too low. I will try to find time to put it back on the lift this weekend and take some pictures of my own.
