I voiced this concern in your DIY thread, so I'll follow up on it as I am curious: did the ducting stay where it was supposed to stay at the right orientation? Even then, it is not clear how effective it will be without the backing plates as the stock plates will most likely block most of the flow. Plus, the stock rotors have not been designed for forced cooling.

Too many hot laps with a 4000lb car does this kind of thing to the brakes I guess. I did end up in the gravel at Watkins Glen despite the upgrades (not that I am a pro driver or anything), and learned this the hard way. Race pads were smoking and fell apart at the paddock.

If you were to say that you have not experienced this issue on another 400hp+ 3700lb+ car (which sells for $60k) when you drove it the same way you drove the M3, then we can blame it on BMW engineering.
