Hi guys, long story so bare with me. I have a 2015 370 Z. I have rotora big brake kit installed for a while now and it's been working fine. I recently had tein Flex Z coilovers installed with EDFC2. After the coilover install I noticed major clunking noise in the front and the rear I called Tein and they told me the upper mount bolt is is not torqued from the factory and they need to torque it to specs. I went back to the shop to have them torque down all four mounts; some of the noise went away but I still had different kind of noises. I did some research here and one of the recommendations was to preload the coilovers I went back to the shop and sure enough they haven't preloaded them. They pre-loaded four coilovers and the clunking noise I had when going over road bumps was gone.

I took the car for a Canyon Drive to test out the new coilovers and the car was pretty responsive big difference from stock coil overs. the next day after my fun drive, I started to hear a grinding / clicking noise from the front passenger wheel. Additionally when I go on ramps like getting to the gas station I occasionally hear clicking noise that sounds like a bad drive shaft on a front wheel drive car, no idea what's causing this noise.

I took the car back to the shop to inspect the noise on the front passenger side, the mechanic told me that the noise is coming from the big brake kit possibly a warped rotors.

I took the car to the rotora shop they inspected all four wheels, they told me that some rocks have gotten into the pads from my Canyon Drive but they're gone and everything is in order. I drive the car back home and sure enough that clicking / grinding noise is still there. I have recorded the noise driving on the highway link to the video below

At this point I don't really know what to do any help or guidance from you guys will be life-saving to me. Thank you in advance
