Mark Donohue and 930 rear suspension

I just got finished reading "The Unfair Advantage" by Mark Donohue and I highly recommend it.

My question is: is the rear suspension pickup modification that he had Porsche do on the 911 the same one that was done on the 930 rear suspension?

Donohue said they raised the inner pivot points which didn't improve the bump steer (why would the rear suspension affect this?) but the car was a lot flatter in the turns.

He had very high praise of the 911 Carrera. When choosing the first IROC cars he wrote: "... the Carrera had to be the most reliable car available."

It's really amazing how little they knew about suspension back then, especially in the late 60's.
