You're right I see a lot of the white M3 .. but not a frozen one! How long will you keep this, and what is the next color on your menu?
I did cold brake in very wet conditions on start ... non noise except very faint grabbing vv. minor high pitched noise - can't tell if from front or back so I take this as 100% fixed. If I can determine the backs are responsible for this very minor noise, then may change backs to softer brand when they are done..
