There's a big difference between a spring that will fail an MOT and a spring that's actually suited to the vehicle it is installed upon though which is the point Piggy's trying to make I think.
I don't know the specifics of an NI MOT but over here on the mainland it's pretty much a case that so long as the spring is seated properly even on full droop, still allows some movement and isn't snapped or heavily corroded then it'll pass. Dampers from memory are evidence of leaking and checking that they have sufficient damping to control movement.
I've not personally measured them but I find it hard to believe that the spring rate and preload would be anything approaching correct on a Saxo spring when fitted to a 306 given the significant difference in axle weights between the two, but equally I don't doubt that it would fit and function to a certain degree.
PS. A car can pass an MOT yet be unsafe and unroadworthy and equally can fail an MOT and yet be both roadworthy and safe.
