Didn't make anywhere near the sort of progress I planned to today, but nevermind...
Jacked the front of the car and placed on axle stands ready to fit front suspension...
Removed the wheels
Fitted the bonnet lifters
Removed the old bonnet stay
Removed the airbox not-MAF pipe and tried to fit RR D585s
...3hrs later, still fitting D585s after removing, airbox, alternator lead, checking 'plugs, googling instructions (cos there aren't any) and trying to imagine what the photos would have looked like if they were still on the RR page, dropping a 10mm nut somewhere (and not finding it)
Then I noticed the passenger front arch liner was cut-off at the bottom, so replaced that with a full arch liner to protect/direct airflow through the n/s cooler
Punched a new hole in the arch flap
just below where it had split (as they all do)
Gave the suspension up as a bad job and road-tested the new coils to find an - unrelated - airbag fault
