Thanks for the help everyone!
You
dont need a spring compressor!
1) crack off wheel nuts, jack up, remove wheel nuts, remove wheels. Use axle stands!
1a) Plus gas the crap out of everything.
2) Then either; remove calliper (two bolts on rear) or disconnect flexi-hose. Note: this requires the brakes to be bled once reconnected. (I clamped the flexi hose but This is being replaced!)
3) Undo the tie-rod nut. use a ball joint splitter to separate this.
4) Release the radius arm at the lower control arm. This requires undoing the three nuts, and levering the radius arm undo around and letting it sit on top.
5) Next undo the two allen-key bolts on the upper wish bones to release the upper wish bone.
6) Lift slightly the lower control arm with a jack under the dampener.
7) Undo the lower bolt that goes through the dampener and lower control arm. NOTE: The spring is now free to roam. Be careful with the jack.
8 )
Slowly lower the jack until the spring is fully released.
9) Undo the nut on top of the dampener. Yes, that is a plastic cap on it. Yes, just pop that off you dont need to unscrew it!

10) Pull out the dampener and spring.
Reassemble more or less in reverse.
If fitting -50mm springs on the front you may want to consider cutting down the bump stops. Here is mine I did:
I cut off the bottom plastic section where it enters the rubber using a hacksaw. THen, I cut off two and a half ribs up. I then reduced the size of the half rib now at the bottom and worked it back into the plastic with some grease.
