Weight of your car and type of damper on the shock will decide what to go for.

What is the point of coilovers if it is just a daily driver? A good set of lowering springs would be the best option.

I'd have a look at the Japanese brands like Tein / Cusco and see how their spring rates change as the coilover progresses from a street unit to a racing unit. I would find a suitable comprimise... Coils with too soft springs will be useless if you want to do any track stuff, too hard will be useless on the road.

For instance, I'm running the Tein Mono Flex in my Evo X which are 12kg front 10kg rear. Stock suspension is 4.2kg front and 3.8kg rear. However the better dampening of the mono tube shock means there isn't much jiggle in the car. It is firmer, but not bone shattering (I can dial up the shocks to bone shattering though).
