Depending on your application is the setup you need. What are you going to do?
The most impact in suspension mods are according to some people are:
Wheels (More contact to the pavement, less flex in the sidewall)Shocks and struts (Firmer better feeling from the road)Strut Tower Bars (Less Flex of the body, cheap mod)Springs (Lower, firmer fill)Suspension Bushings (??)Swaybards or AntiRoll bars ( to eliminate understeer or oversteer, and/or to feel flat on the street (i forgot the word)
instead of the shocks and struts + spring combo, you can buy coilovers, cheap coilovers are just for looks, NOT for handling, good coilovers (that almost always cost $1000 or more) can be tweaked to the special need in the moment. Do you need that much tweaking???
Over this list, I would add tires to the top. It's the only 4 things holding the car to the ground.
As far as suspension tuning, it is important to remember that it is not what kind of parts you have on your car. It's really how those parts work together. And like most things on a car, everything tends to compromise something else. I would also move wheels down on the list quite a bit. And I am assuming you are referring to larger wheels. There are plenty of tires out there that have very stiff sidewalls and even with relatively small wheels would still give really good response. Secondly, wheels tend to add more unsprung weight and rotational mass. But then again, bigger wheels tend to look better.
Lowering springs can help, but you want to make sure the shock used with them can control the movements, and that it is not so low as to take away too much suspension travel. Bottoming out a suspension is a quick way to transfer weight to that wheel and cause a loss of control. Particularly in the front suspension of a 240sx. And firmess is not always a good thing. It really depends on the use. This goes for both the shocks and spring. If roads could be perfect, there would be no need for a suspension.
And as far as adjustable coilover set-ups, unless you want to cornerweight the car everytime you make a change to ride-height, I would not recommend these. If you don't properly cornerweight the vehicle, the car may have strange handling characteristics.
