Default Ride height question...

Let's say I want to increase the ride height by 10mm. Would I raise the threaded adjuster by the same amount? I gues I'm asking is there a 1:1 relationship?

Andrew-- 10mm in the front? Front takes about 2-3 turns for 10mm ride height change. It's hard to say because it take some driving to see the effect.

Why do you want to raise it?

No, measure the length of the A-arm, measure the distance the coilover is from an end, do the math, and you'll get close enough.

It's a bit too low in front and I'm going in for an alignment... I mean Doctors appointment on Thursday.

LF 148 | RF 153
--------------------
LR 161 | RR 162

I think the rear is okay, but want the fronts at 163.

I started cranking up the LF thinking I needed to raise it 15mm, but then started wondering if it's a 1:1. Thanks to Zeus's linkage, it's a 2:1 relationship. 1mm of adjuster travel results in 2mm of ride height.

It's not 1:1. I think I found 1:1.5, but it depends on your springs to some extent. Use 1:2 and see if that's enough.

I agree with raising the front. No more bottoming and I feel the handling is better in the mid-160s.

I was going to make some bad joke about wanting the car to sit at the correct ride height (level) once you were in the car.....
