Does any of the factory spoilers(trunk lip spoiler) actually help with aerodynamics?

On a 328i? Um, no. Not even at 150mph. The BMW Performance Aero package, in full, provides a bit of an improvement in rear end lift at speeds near 150mph but isn't of any real use otherwise. The 328i isn't quick enough to make use of aero on the track either.

The Aero package includes rocker covers and a trunklid spoiler as a complete wind tunnel tested package. It's speed dependent not acceleration dependent so unless your car greatly exceeds 155mph it won't make any difference to the Aero pkg's efficacy. And it has virtually no effect below 100mph or so anyway.

Understood. I'm using it because corner entry exceeds 100mph so it can help a bit and the two scoops in the front bumper were perfect for the oil cooler and CAI.
