Its not neccesarily the best route simply because you can get exactly the same spring rates and damping rates on a conventional damper, the coilover allows height adj as the only benefit.
This is in our case, in the likes of racing cars they offer you a single step progessive spring rate if your running a tender sping, height adj, onboard remote adj of daming rates, far more adjusment to ihgh and low speed damping and a smaller lighter body with lighter spring.
back to our case, the actual physical setup wont offer any benefit IF both the coilover and conventional damper have exactly the same properties.
I dont know any of the specs apart from what some people like to run as spring rates, but even those spring rates seem low to me.......
You can only do so much playing with dampers and springs, but for most thats enough.
