Just thinking, if you need to know if you are on level ground, can you test this with the car?

1. Go into Off Road Height which activates the cross linking

2. Allow the car to settle

3. Measure bottom of rim to wing for fronts and backs

4. If measurements match for fronts, and for backs you are on level ground

At least for left and right!

5. Turn car 90 degrees to check the other plane.

Joe what job do you do??

I need one like yours so i can get some more free time

It sounds good in theory b ut not many places have level ground as it all slopes off by a few degree's to aid run off..

Working in Facilities (providing service to others) means that time off is precious and saved for repairing one's FFRR and posting on this forum Plus Strictly is on (SWMBO!) and I have reached my boredom threshold after two dances this week - usually manage three  .

A FFRR is a hell of a size of spirit level.
I'm sure someone must have invented something smaller possibly using oil and bent glass tubes.
I do like an inventive mind though.
