Can someone explain to me the difference between standard strut and spring set up and coilovers and what works best?

 

I have Tein on the car at present, low and bloody firm and can't decide wether to keep it that way.... great on decent roads and cornering.....but boneshaking on the crap country roads and a cause of nodding dog syndrome on the motorway! It's a second car so I don't spend hours in it and i think my thoughts on changing it are a little clouded by the great ride of my 350Z on standard set up.

 

Might be better to throw the money at better brakes first!

Coil overs are really meant for racing and track work (though obviously can be used on the Road)- infinitely variable/ adjustable ride height and damping from firm to rock hard.

Standard-ish set-up is far better for comfort and day to day driving.

 

I have adjustable coil overs and I am changing them for -20mm springs and adjustable (std type)KYB shockers.
