Good work as always dude.
One thing tho, shorter springs won't give you more travel tho. All it does is move the platform up (assuming you want the same ride height. Think of it this way - if you've lowered your car so its on the bump stops for example, and the adjuster is at the bottom of the thread. fitting a shorter spring won't mean it will go any lower.
To create more piston travel at that ride height you will need to raise the top mounting point (or lower the bottom).
