First off id like to say that coilover depot is the best to deal with customer service is top notch . Just issue with BC So i put am in and just keep having a clunk noise in front and did everything they say could cause it but noise still there idk i was just better off leaving my konis on with h&r springs about same drop in height so idk feel like i just pissed a grand away
I've had my coils on my car for about a week now and the front coilovers are good and ride nice. The rear will not stop bouncing I've tightened the spring and loosened it. It just adds tensions. I wouldn't expect the stock spring to be this bad. I can't hit bumps without my car bouncing 10 more times after 1 bump. They fit well and work for my car very well.
Have you adjusted the rear damping with the damping knobs? That would help improve ride quality. I would try to adjust the spring preload to 6-10mm as recommended by BC racing. We have a video on setting the preload under the tech info tab on our site.
