chances are the Monroe shocks are not the cause of the hard ride. I've heard alot of things said about Monroes, but never that they are too hard. But even a standard 1200 has a harsh ride.

A set of variable rate front coils combined with the shocks you've got will absolutely transform the car. Best ride/handling compromise you'll find for the 1200. Did you get Holden Gemini's (Opel Kadet) in NZ? Front coils out of them can be used for this purpose - they're the same diametre as 1200 coils and are variable rate. They have to be cut, but if done sensibly can remain captive at full extension, and once you drive it you'll wonder why aftermarket spring manufacturers don't make em like this for the 1200!
