Is it possible to retrofit the Sport suspension calibration on a standard 328i?

Calibration? Do you mean alignment or the whole sport suspension? Well the answer to both is yes but I would not reccomend the first since it's not designed for that alignment. Run a search on sport suspension retrofit and you'll find out what you need to retrofit it on your car. Lots of people sell their used sport suspension on the marketplace here. If you want, you can go with performance suspension as well.

I was simply looking at the 2007 3 series brochure and the options listed, and that's exactly how it was stated. So I don't see how the car isn't designed for it.

Read my post more carefully. I said the sport alignment was not made to be used on a non sport car. The sport suspension has stiffer shocks, springs and sway bars. It also sits lower. Most of the hardware is still the same. So again, yes, you can put the sport suspension on your car. Many people have already performed a retrofit. Just don't put the sport alignment on your non-sport car. You'll get really uneven tire ware and different handling.
