Forgot about updating this after I fitted the sportlines.
It was really easy to be honest as long as you have the right tools.
First the rears don't even need me to comment on, 5 mins maximum for each side.
As for the front, I started by removing the track rod and drop links, the drop link ball joints kept spinning so I ended up butchering them and fitting new ones at £9.50 a side. The bottom ball joint was then separated from the wishbone by removing the 3 securing nuts. I then decided to remove the suspension assembley and hub as a whole. This was done by removing the brake Caliper, undoing the hub axle bolt and the 3 bolts at the top (under the bonnet). I could then pull the drive shaft out the back of the hub and remove the suspension assembly. I was then able to used spring compressors to change springs on the bench.
As for refitting it was just the opposite to removal.
Hope this can
help someone else in the future
