Churchy,
Yes I did change the rear springs but that was because Ian originally supplied me with front springs for the rear. He swapped them over no charge.
So the short answer is that Iam using springs as recommended by Ian.
Only change I made was to machine up aluminium spacer to go between the two springs in place of the neoprene spacer that tends to extrude.

PS did I mention there is only 59 sleeps to the Nationals.
