I just noticed a noise coming from my left driver side wheel. It sounds as if the rotor is scratching along the inside of the caliper, could the problem be caused by my coilovers? I didn't hear the noise before the coilover install. The car is dropped roughly two inches or so if that matters.

 

I have that same problem, but i didn't install my coils as yet. I'm actually taking it back to the dealer before i do the install. I'm thinking it's just my back brakes, but not sure how to check without me replacing the pads.

 

It's probably your backing plate. Take your wheel off and push it back. They're very flimsy and easy to bend. I bent mind out on place twice once while dropping the car and again while changing my bearings.

 

i had the same problem when i first installed my eibach springs and spacers. after i tightened everything up after the 100 miles the sound was gone. not sure if you're using wheel spacers, but it could also be possible that they were not tightened properly and are a little loose.

Yeah I took it to the dealership and they found out the backing plate was causing the noise. Thanks everyone!
