I'm seriously considering buying this.
The OEM 1M air ducts fit the 1M style bumper
for the M3. This has been verified here:

So is it ok to assume the OEM 1M ducts will fit the 1M style bumper for a non-M? Don't mind if its not a straight fit, there will obviously be some modifications required. Looking at pictures both the 1M bumpers for the non-M and M3 look the same, apart from the width of the arches. Looks like the main air duct portion/hole is similar?
