BMW put it there to make it different from the 128i. For the same reason my ZHP has it and normal 330i's dont. Its part of the M-Package body kit...
I really doubt it helps hold the rear in place at high speeds, but I could be wrong. I'm not sure what the normal 330i has for a speed limiter, but my ZHP is at 155 and I've been there. Maybe 155mph limited cars are suppose to have it? My car felt solid, but so did my buddies e90 325i (`06) ZSP without a lip on the trunk...
I'm sure its just adhesive, so get you some fishing line and a heat gun. Not too hot though, you dont want to buble the paint...
I like it, but I'm partial too as my ZHP has one similar to it...
