When it comes to springs, work with one corner at a time. Fix the ride height back to where it was prior to the spring change. Once you
get the spring you want in the setup, you might have to cross the car out to make the preloads correct. It took me a little while to
understand how this works. Just keep messing with it and you'll understand what changes make the right adjustments.
If you're not sure how to cross the car out. Basically if the cross weight is too high or too low, you can adjust the spring perch
to reflect which way you need to go. If the cross weight is too low you would add a click or 2 into the LR, take a click or 2 out of
the RR, Add a click or 2 to the RF and take a click or 2 out of the LF. This is also a good tuning method if you need to be just a
little looser or tighter. Keep in mind that you wont always move each side the same amount of clicks. A stiffer spring requires
less movement to notice a difference, where a softer spring would require more to notice a difference.

The videos on this page should help you understanding the adjustments. Since the video was made iRacing has had an update or two, so you
may find that things are not quite as the video suggests, however, you will get the basic idea and with a bit of patience you will get
to where you need to be.
If you've tried some of the spring settings suggested above but are having problems with the ride height tolerances as well as the
front and rear preload remember to disconnect the front ARB when making adjustments. After you have made your spring changes and
re-adjusted your ride hights back to where they where, reconnect the bar and click apply.
