599 Lowering Issue

Hello group. I recently purchased a 2008 599 with only 5K on it. I decided to lower it, as I have read the thread that it's easily done with the coilovers, but after taking a look at it, my front swaybar is almost next to the coilver and there is no room to lower, so I decided to get H&R springs.

After, I replaced the springs, I started getting major knocking noise. I took the coilvers out inspected them and double checked and placed them back on, and there is no issue and noise continued. After inspecting more, i noticed the front and rear swaybars bushing were dryied up so I decided to get H&R swaybars. I replaced the swaybars and went for the drive. The noise was lot less, but I am still getting a clicking type of noise. I inspected everything again and I can't find where it is coming from?

Has anyone had any experience with the springs after changing to get this noise?
