The simple fact is pound for pound, you'll get better parts with a shock/spring kit than you will with coilovers. The whole idea of coilovers is flawed IMO. You cant have adjustable height without adjustable rate. If you lower the car, you need stiffer springs, or it bottoms out. With retail packaged coilovers, you get one spring, which is stiff enough to allow you to run it at the lowest available setting (ie on its ring), which in turn is almost certainly not ideal if your running it at a much higher sensible height. Or they make them more comfortable by fitting softer springs, which then gives you a much narrower range of adjustment before its so low it bottoms out over bumps. On a race car, the coilovers will be designed such that they will use standard size springs available in a huge wide range of lengths and stiffness, allowing you to fine tune the springs to the car and the desired height. The damper valving is then adjustable to fine tune the damper response to match the chosen spring. On a road car, most people dont want to have to learn about suspension, spring rates, damper valving etc etc, they want something that simply bolts on and works, and in that vein, a properly designed spring/shock kit, thats been carefully produced to match the car, and designed to work well at its chosen height will offer the optimal end result. The problem is many folk who buy coilovers, espeically the cheaper ones, buy them not because they want a car that drives and handles correctly, but because they want it on its arse and actually BELIEVE that hard as nails, on-its-ring suspension is actually desirable and makes the car handle better. The products are then designed for this market. You get the old faithful "Handles like its on rails" wheeled out, and folk think its the dogs danglies, when infact its probably now slower than it was on the stock springs/dampers which actually worked properly.
