I go round and round with that question Ricky. I never had the chance to track it after installing the BBK. Plus, these brakes only have about 6,000 DD miles on it. Right after initial install of the BBK last November with 12mm spacers for the OEM 18" to clear the calipers, it all of a sudden had a slight vibe at about 80+mph. but it did not feel magnified with braking. That started to happen about 3 months ago, or at least I noticed it about then.
I'm pretty sure if I can remember correctly, while I was in England with this M3 and had the BBK installed. I regularly cruised at 95+mph on the motorway there and braking didn't cause this issue, although I had the slight vibration/wobble in the steering wheel. Must have just started to ware like this I guess. Kinda strange though.
