coilovers do not have to be used to adjustable struts. especially the gc coilovers which are one of the best coilovers out. they have the best overall quality, handling, etc. when you get coilovers you should change out the struts because they put more stress on your factory ones that they are not used to but you could just replace with a stiff non-adjustable.Rogue6 said:Coil overs shoud only be used w/ adjustable shocks. The E's were designed to use the factory (but good') shocks. They offer the best 'bang for the buck' but coil overs let you adjust the car to climate, personality, racing, autoX, and girlfriends (w/ adjustable shocks).
