Really...this has been discussed to death b4.But where REALLY,is the best location to put the axle stands on the rear so that you can work uninterrupted?Plse don't tell me to put it on the subframe(though that's the best location IMHO)coz I know for sure the 2 rear subframe bushes will tear under the load of the e34.
The weight of the e34 is actually carried by the strut tower.
