Jacking Up All Fours Techique

I'm involved in a few "get it back" ur-quattro projects at the moment - sensible, well-funded,
middle-aged owners who are trying to get their ur-quattros back to factory specification.
Most - oddly - are 1988 cars.  The MC engine turns the ur-quattro into an amazingly driveable
car.

One just had ALL the rubber in the suspension replaced.  I advised that he should drive the
car for a couple of hundred miles and then take it for a proper 4-wheel alignment.  He took it
to Roger Galvin for this to be done.

A couple of weeks later he asked me to test-drive the car.  It was a PoS.  My party trick in
the Torsen ur-quattro is a controlled slide balancing the ends of the car on the throttle.  No
chance - the car felt dangerous.

I was about to slame Roger's technical ability when the owner said he'd just had new tyres
fitted.  So I grovelled underneath, and sure enough - trolley jack marks on the subframes.
Kwik-Fit. The alignment was utterly ruined.

But the annoying thing?

THAT'S EXACTLY WHAT IT SAYS IN THE WORKSHOP MANUAL.  LIFT THE CAR BY THE SUBFRAME AND YOU
****-UP THE ALIGNMENT!
