The local (very successful) mini tuner said there were two methods, one of which involved a scale which could handle the weight of the front end. The other involved a torque wrench and a slip of paper. The idea is to get both corners (at each end) weighing the same - imagine a table with one leg shorter, same principle. From memory, it involved measuring the torque required for a wheel to lift sufficiently for the slip of paper to come free from under the wheel. You needed a bit of leverage obviously, but you balance each side and then equally adjust ride height to suit.

The rear is a bit easier as it weighs a lot less, so you should be able to find a set of household scales to measure each side (with the other side lifted by blocks to the same height.

This is just theory for me at the moment as Hi-Los (in NZ) require certification so a bit of legal hassle. But it is, I believe, more than just measuring the height above the wheel to the wheel arch. It makes sense and I believe the results would be well worth it.

Anyone else?

Most hi-lo's are a simple nut and bolt arrangement, lengthen the bolt - raise the car
shorten it - lower it,
just unlock the lock nut with the weight off the wheel, turn the bolt to where you think you want it, lock it up and see what it looks like on the ground. Remember it may lower itself a little after a test drive. Keep playing till you get your desired height

Questions..Where do you have the Torque wrench connected to and is this while the car is on the ground or just off the ground
I understand the Table Idea

You put the torque wrench on the hub nut, see what torque it takes to make the wheel skid on the paper. :wink:
Then repeat for the other side.
NOTE: floor must be FLAT!

Hmmmm Interesting :shock:
You would have to have it perfectly balanced then
