I hope you have more than a 1.5Kg jack!Maybe a 1500kg,or a 1.5 ton jack!!![:I][:D]
Anyway,i jack mine up on the front wishbones.Slide the jack in behind the front wheels,towards the center of the wheels.You will see a fairly flat area,with indents & boltheads on the wishbones.Thats where i jack mine.Although as the suspension has to be on max high,the car tends to get a bit unbalenced.Chock the rear wheels.I prefer ramps myself.But as your doing a sphere,& releasing the pressure,i supose the car will be on max low.Put the jack under 1sr before lowering it.
