there were no noises whatsoever before this happen

I adjusted the height on my pro damper coilover on my 06 z , and i loosen the very bottom perch collar of the shock to lower the shock body and i didnt mess with the spring preload perch at all. after that i turn the whole shock body clock-wise to lower the whole body of the shock to desire hieght ,i started on the passenger side first and i did the same damn thing to the rear driver side , and i tighten everything to where it suppose to, after that take it for a test drive and there were loud thudding noises every single time i went over small and most tiniest bump,and it sound like a thudding noise like something is loose on the top of the coils ...and tight. THe only place i havent check is the lock bolt on top of the coils or the two bolt that secure the coils over , in order to do that i have to take the coils out completely , it only happen on the rear driver side , the passenger rear is ok and normal

spoke to ksport this morning and they said , they are very sure that i wont be having a blown shock because if i do , i would have fluid everywhere but no fluid can be seen .
please help thank in advance , hope some other individual have the same problem as me and have already solve it

it prob this reason ? it sound almost like this ... when over bumps is bouncing up and down ..but just more severe......

Double check the top 19mm nut and make sure it is torque'd to 40 ft lbs. They should be tight from the factory but I would double check it just to make sure. The nice thing about the rear true coilover is that it only takes like 30 seconds to pull it out.

I have Ksport Slide Kontrol's in my 07 Z and also had the Kontrol Pro's in my old 03 Z. Never experienced any noises from the coilovers in either car.
