If you go aftermarket, you run the risk of bad fitment of the sensors, tow hook and washer covers like in the picture you posted. The paint match is also pretty bad.
The M Sport bumper is a simple bolt on with some minor part changes, and a complete retrofit kit is available from getbmwparts.com. They can even paint it.
I try to be helpful around here but I really don't appreciate being referred to as a troll for having an opinion.
Thanks for your input, wdimagineer. Both of the bumpers were going to be non-oem and aftermarket. I wasn't calling you a troll, I just saw the fake m5 thread a few minutes before I posted this. I didn't want people to think I was trying to pose as a M5.
