After some correspondence Andreas at Simon Auto assured me that the springs were correct and upon checking closer it did seem that they would fit so I took the plunge and had some bottom springs carriers made at work and dismantled the car. Here are the new (blue) and old (black) springs,

Here is a photo of the finished installation.

Does anyone else have these type of springs on their A310 - they upper mount says Spax M73E and from the internet some links come through to Cobra replicas?
