is it a standard 200 you have?
mine is a standard 200, and i found that as the shocks are 30% softer than the cup shocks, the standard springs were too much for them, which resulted in quite a bouncy ride. U'd go up and down a few times after a big bump if you know what i mean.
I changed mine to cup dampers with the H&R springs and yes it is much stiffer on the shocks, but the springs dont seem too much different. They are definately not as harsh as the cup springs.
With my limited suspension knowledge, i would say you would not only see, but feel an improvement if you put the H&R springs on standard shocks. The springs dont have as much travel so you should in theory get less bounce back effect on bumps.
If you are planning on fitting them yourself then for the price of the springs you dont have alot to lose.
