Lowering Question

I have a ‘23 HTC Z51 without the adjustable front lift option. I’d like to lower the front slightly (1/2” ?). How much height change do you get from 1 turn of the coil collar? Of said another way, how much do you turn the collar to achieve 1/2”
drop? Thx.

I got the same result. Adjusted all the way down was .75".

Hopefully this helps you figure out a 1/2 inch. Good luck!

I lowered mine all the away around - Non-Z51 with mag ride, no front lift. I do have wheel spacers however.

The track prep guide says each full turn of the spring seat is 0.06” (1.5 mm) of ride height adjustment.
