-Lightweight carpet: 17 lb
-Thinner windshield glass: 20 lb
-CF hood , bumpers and side "blades": 29 lb
-Battery: 21 lb
-Intake and sound insulation: 11 lb
-Carbon ceramic brakes: 20 lb

This already totals almost 190 lb, well above the upper limit of the number I've estimated for the M3 reductions. Of course I'm pretty sure the next gen M3 is not going to get CC brakes, but either way the numbers I have posted are totally realistic.
I don't know the seats they used in Audi R8 GT, but I assume they're carbonfibre racing seats. And the big chunk of the savings are coming from the seats. BMW will NEVER put seats like that in a standard M3. Nor thinner windsield glass.
