RPG 1.5” collar springs… level or not?

Here is my stock 37 with an empty tank, I'm looking to do the RPG 1.5" kit once my film work is done, I'll report back the measurements before/after with a full tank of gas.

Do you have measurements from ground to center wheel well?

Measured to the center of the fender flare from the ground. The measurement is the same on both sides. It sits .25” higher in the rear on both sides.
