Yeah, the original write up I did in this thread was on my previous 335i but I did mount the same license plate bracket on my 335is. It pretty much went in the same as my last car. I did use self tapping screws but you still need to get a small drill bit and start off a hole by hand, DO NOT USE A DRILL. Make sure the bit is smaller than the threads of the self tapping screws or else the hole will be too big for them to bite into the bumper. I tried without making a pilot hole first but it just wasn't working out. The plastic is not like wood or metal, it's too slippery for the self tapping screws to really grab hold.
