As to corner balancing, some people don't like it as the ride "can" appear to not be level due to the weight distribution. You either live with a side being as much as an inch different, adjust it back to level or weight the high side.
Corner balance isn't about a high side, it's about a high corner. The goal is to even out cross weight pair % - LF&RR to RF&LR. Like sticking a packet of sugar under the wobbly table at the restaurant. You can't really adjust a left side only % or front only with a corner balance.

A car that's out of corner balance will handle differently on RH and LH turns. Slightly different cross weights will equal slightly different handling in each direction, which can be harmless. Way out of whack and the car can become dangerous to drive.

After swapping torsion bars and "guessing" on heights, here's how out of whack I was:


56% LR/RF cross weight meant the car was crazy loose on left hand turns.

A little lowering of the RF only and:



Boom, nearly perfect 50:50 cross weights, and a much better driving car. Note no matter what corner I raise / lower I'd never get the LH total to match the RH total, I'd have to move ballast around inside the car to accomplish that.

And to the OP - the 911, especially the rear, is a major PITA to align. Changing heights is going to require an alignment, but you can't take it to your local tire shop. You'll need to find a shop familiar with old 911s. And you'll probably have to pay a little extra for that knowledge.
