So my BC racing front right coil magically lowered itself an inch and caused my wheel to hit my fender and crack the little bit of bondo to smooth over my pulled fender. Has anyone ever experienced this magic adjusting coilover

 

I'm sorry this happened to you.
How long have the coilovers been on the car? Who did the install?

This is very unlikely the coilover would be faulty in this manner.
I'd strongly suggest making sure that all of the collars are tight on all 4 corners as soon as possible.

 

Do the collars not lock? Are you not running Torrington bearings?
