I noticed they were a little noisy as the spring would move around a bit which caused some some spring noise and little clunks when driving over the bumps. I also have a friend with an Integra with coil overs and he has said his coilovers also have similar characteristics. So, I wonder if all coilovers do this or is it just the few I have ran into? But something I would ask about.
That doesn't "sound"
right... The spring in a coil-over-damper is captive and normally under tension. Like a normal separate-spring-and-damper arrangement, actually. The only time the spring can rattle is at full droop when the damper is at full extension.
Some coil-overs have a "tender spring" on the end of the main spring. A tender spring is an overly soft multi-coil spring that would normally be completely coil bound because the main spring's rate is vastly greater. When the damper approaches full extension, the tender spring starts to unwind and keeps the main spring from flopping about.
In any case, if a coil-over rattles, there's something wrong somewhere: something's loose, due to incorrect installation, for example, or maybe due to crappy quality resulting in too much clearance in wrong places.
