As it says really. Just made some blocks out of 30 mm od nylon bar. Jacked up stuck them in and took the actual heights then fed them into the saved data for each height. Worked a treat, who ever had done it before had not balanced the back properly, it sagged to the back drivers side whenever in motorway level, recalibrating sorted it out. Thanks to the nanocom EVO.

Did you machine them 100mm/105mm F/R ?

Thought about cutting them of in the lathe, but just used a band saw and a square to keep them straight.
All in mm.
Front back
Extended 140. 145
Standard. 100. 105
Motor way 75. 80

Didn't bother with access, left it alone. They are 35 and 40 respectively.
