Could be your lug bolts are on too tight. The whole hub will warp at 120lb-ft, the rotor could warp even sooner. Spec is 80lb-ft.

In Hong Kong, no one will care about the torque spec of wheel nut. Just only apply the torque gun.

EXACTLY. Especially after wet conditions, and yes it can be loud indeed !

What is the cause of this though ? ANything I should worry about ?

Mine like this too, esp after washing the car and idle for few days w/o use. The moisture ceases up the rotor surface and wheel hub.

I appreciate the detailed response eldiablo.

Well, in fact, I am not the one who suggested the warping first, I had left my car at my friendly garage specialist for some upgrades during my holiday, when upon my return he said that he noticed that when braking, "the car would have some slight vibration, generally a symptom of warped rotors".
I then drove the car and paid attention, and indeed this is the case. Well, since I didn't notice it before he told me, it is not "that" serious. Yes, the car is vibrating yes, with some strange noise as well.

Unlike you however, in my opinion the car doesn't stop as well as before. I know because there is this straight line near my house, where I know what speed I reach (fast) and when exactly, at which point I need to break just in time before reaching the roundabout in the end, and one day it almost ended badly :D. For my casual driving to and from work, the brakes work absolutely fine enough. But their efficiency has decreased, I think I can tell.

I am also concerned that the vibration may damage other parts of my car in the long run.

Check any blue surface or grooves on rotor surface.

I'm from HK too(but no longer live there), I think its really hard to do DIY stuff in HK since not everyone have a garage to work in. Still maybe you guys can get a torque wrench and put it in the trunk just in case? lol
