I have a 99 Civic SI, with skunk 2 coilovers. I was driving one day, and while cornering and heard a rubbing noise. It got progressively worse, and then stopped completely. At the time I didn't think about it, but I did hear something small fall off. Now it has been replaced by a squeaking noise whenever the strut is surpressed.

Someone said it could have been a bumpstop or something? I have no experience with suspension, so I am clueless.

 

Depends. I have a clunk too, happens when I corner hard. Still can't figure it out, but it's probably the trailing arm bushing.

Anyways, it's hard to tell. We need more details.

 

If your car is lowered, it's probably the suspension bushings. Did you reset them all after you lowered the car (to relieve the twist)? It so, then it's probably due to the trailing arm bushings deteriorating since they cannot be reset. You can tell by just looking in the wheel well and checking for cracks or tears. When it comes time to replace them, make sure to "clock" them to your new ride height, and it won't happen again (as long as you maintain the same ride height).

My clunk is my swaybar endlinks contacting the shock when the swaybar itself shifts slightly left to right. I only noticed this because I painted my Konis black (to hide them, its a daily driver), and the black paint has been removed from the contact, but the yellow paint is still completely intact. I don't think I would have been able to easily identify this without the black paint, as the shock itself is not dented or showing any other sign of impact, and the Koni paint seems strong enough to not rub down from this.

I also have a squeaking noise from back there, but I'm assuming that its from my polyurethane swaybar bushings. I did not have the noise after install, but it has slowly developed over the last year since then.

My Ground Control extended upper shock mounts also produce a squeaking noise. I believe the supplied "bushing" that separates the spring from the mount is poly, and is causing the noise when the spring twists during compression. I only have these in the front, and I have had this noise since install, but it has also increased in volume over time.

My car only has 63k miles, and has only been lowered 1 year, and already I am seeing small cracks forming in the RTA bushings. If/when this will contribute to noises, I don't know, but I would definitely check and replace as needed all bushings and reset / clock as suggested by 94eg.
