Stijn,
Oil line is off, just the tranny ground strap remains, fan and shroud, but otherwise, I'm ready for the drop.
To get the rear higher, I'll remove the wooden blocks under the front suspension nail them together so they make a solid base and put them under the jackstands in the rear. This should be good for another 10cm (thats about 4 inches for you Americans...

)
Oil absorbing rags should be present on Firday as well so no kitty litter stuff.
