I've had Eibach Pro-kits and Eibach camber kit on my car for some time. The springs for over 3 years. Never had any clunking ever?

My friends stock lude had some clunking under warranty. The cause was that the rear strut isolator bushing wear over time prematurely on most 97+ Ludes. Not sure if this is much help but its the only clunking I can ever recall hearing in a honda.
