Thanks for the info- it does help a bit.
Has anyone actually moved their front subframe??? The above instructions appear to be doing the drive train alignment (after an engine removal perhaps?)- is this necessary for a small alignment change?
I've done the rear subframe alignment (only slightly out) and the car does appear to track better and hold it's line over bumps better. I know a wheel alignment is also needed, so I'm getting that done next week (toe set as close to zero degrees as possible for both F & R appears to be the consensus for optimum handling)
