No, tires are staying the same for a while. The new MS2 rubber in the incentive not to mention the 25 MPG fuel economy!
Now the question of the springs. I am not following what this will solve. You want me to measure my custom arch to see if your springs are sagging? I will tell you right now, compared to mine, yours would SEEM like they are even if they are not!
Due to the custom arch I have on mine (for the 1" lift plus the load I wanted on them) unless you are measuring the same spec'd spring, it will not read the same.
If you would like I can measure for you, I just wanted to make sure I am following what you want!
Yes I am trying to figure out if my stock springs have lost arch, using wheel arch measurements and body lines to measure adds into the mix tires size etc. I was hoping that since your springs are 1. new and 2. a known lift (1" over stock) that a measurement of the arch while they are on the truck would give me something to compare to. In theory I could take the arch measurement from your spring, subtract an inch and have a "stock" spring arch measurement to compare with.
My interest in spring arch started after I installed the Softride 2" front springs, the truck now sits tail down. Everything I have read says that the 93 should have several inches of rake due to the 6" rear blocks (2" front springs should have leveled it). The way my truck sits tail down I am either getting more than 2" front lift, or my rear springs are worn out.
I don't want to assume my rear springs are sagging and buy new replacements just to find out it didn't fix the problem. I also don't want to buy 2" rear lift springs and sit really tall in the rear because my stock springs were worn out and I ended up with 4-5" of lift over the current springs.
I could also go air ride in the rear and eliminate the need to know about my rear leaves... ... ... . That won't be for a couple years though.
Thanks for your help Robert
