Here is the key factor to me. All the Espo Springs that I have installed in 4 Darts are high when they first go in and understandably settle down in the first couple years (depending on how much you drive it and how much of a load you put in it). I find that +2 is where I want it to be after all is settled out. The same thing happened to all these cars with the stock springs and then they were too low and too squishy.
