And the answer is--------drumroll.

LRA's manufacturer incorrectly painted a batch of springs blue instead of green.

The ones they sent me are actually green springs which are about 20MM longer than blue should be.

So if you have recently purchased a pair of blue springs and think your car sits too high at the front, that is the reason.
LRA are sending me a new set of correct ones, so if you have the wrong ones you are faced with once again removing them.
