Switching from spacer kit to Bilstein 5100s, Truck height questions

Greetings, I own a 2015 SR5 4x4 , riding on 305/55/R20s, that has a spacer kit the previous owner put on it( it’s a 2 or 3 inch see link below for thread and pictures https://www.tundras.com/threads/what-is-this-suspension-on-my-tundra.124862/) .

It’s used off road at my hunting lease and it’s not a daily driver however I drive 130 miles each way to my hunting club. As you can imagine the spacer kit doesn’t give the most ideal ride and I would like to switch it out.

I am pretty set on the adjustable Bilstein 5100s and I want to run them on the highest setting. My trucks height from ground to fender is 40.3 “ currently with this set up and I like the stance and ground clearance for the type of off-roading I do.

1. With the Bilstein 5100 at the highest setting and my current wheel and tire set up, what can I expect the ground to Fender height to be if I go with the bilsteins? How much height will I lose?

 

The highest settings is around 2.5" if I remember it correctly.
