    I’ve been setting the ride height in my car, and took it to get alignmend today and verify heights on their nice level lift. Beats measuring on my concrete garage floor. After doing so, the camber was great and perfect, and we went ahead and set toe for now, but I learned (and expected) that I need to make a few final adjustments to the height in the front +2mm and rear +6mm, then I can take it back to the alignment shop and double check the height again, set camber this time, and set the toe again, and wrap this up. Does anyone here know how much it changes per turn? I know it is not a 1:1 ratio, and I’ve been having a tricky time figuring it out exactly. It would save me a ton of time if I knew the exact number. Thanks for any help.

    I'm not an engineer (nor play one on TV) but if you measure the thread height, wouldn't one turn equal that?

    No. It’s a ratio. I’ve looked only and found everything from a ratio of 0.7, which would be about 2.6mm per turn, and also read 12 turns equals 4mm. Huge difference. I honestly had a hard time telling myself and just wish the WSM listed something. Would make sense, but it does not. I can figure it out, but I prefer to pay for only 1 more alignment. Not 10. I’m also super tired of removing coilovers, adjusting height, driving, adding 350lbs of weights, measuring, repeat. Would prefer to do it 1 more time. Not 10. Haha.

    Why are you removing coilovers to adjust height?

    Park it on your garage floor. Measure from ground to fender. Mark the exact spot the car is parked with tape/etc. Make your adjustments, go for a drive, park it back in that exact spot. Measure again. That should work if you’re looking to raise it an equal amount on both sides, regardless of whether or not the floor is level/etc.

    Front and rear motion ratio is slightly different. If you can find my project thread it's listed somewhere in a recent update.

    I remove the coilovers to adjust height to make raising and lowering the perch much easier. I don't want to strip the threads on the coilover body either. Removing them is the easy part once the car is up and wheels off anyways.

    Thank you. I just finished adjusting it and I was getting around that number. Thank you for confirming! Moved the rears up 2 full turns and am going to raise the front 1/2 turn each tonight, then go finish up the alignment tomorrow morning. Set right at 103/123.
