Hopefully someone can give me some insight here.

Our clio has Spax coilovers (very limited options because of Renault's wonderful Cup suspension) with springs which were ok until we got used to the car and got quicker.

The springs are far too soft, at least on the front, the car squats down and I'm pretty sure it bottoms out on the springs and skips across the surface.

There is another version of the coilovers available but they're £1018, come with shorter springs with higher rates.

Does anyone have any way of determining spring rates? I really don't want to go too stiff and ruin it completely but at the same time, I don't want to not go stiff enough and be £100 down for the springs which are useless!

Spax have been no help in this by the way, they will not tell me what the spring rates are, even though I paid £800 for the coilovers! Apparently it's sensitive information :-/
