When you opt for the V6 you end with automatic only, the cadillac auto isn't the same as DCT or DSG.

Wait, what? MRC FE3 suspension in the ATS is absolutely a performance feature and DOES translate to better handling. Brembo brakes DO decrease stopping distance and fade and are without a doubt a performance feature. What weight are you talking about? This car is roughly 3,500 lbs when equipped with the auto and 3.6 V6, one of the lightest sedans in this class. The LSD is also a performance feature that you will not find in any F30 outside of the upcoming M. While staggered set up does not provide a huge benefit, it does increase traction. Only downside is the lack of a 6 speed manual in the 6 cylinder model. As far as the DCT/DSG goes, yes they shift a bit more quicker than a modern steptronic but real world difference is smaller then you may think and the maintenance is a nightmare.

I hope it is that way, but I can't confirm because BMW USA build your own doesn't seem to be working today; maybe I have a blocker of some sort on, IDK. But if BMW does have a separate package, then hopefully Cadillac will follow suit.

BMW now has a complete line of M-Performance parts for the F30 3-series, including springs, sway bars, etc. They have to be added to the car after purchase; they don't show up in the Build Your Own site. I've just ordered a 2013 F30 335i M-Sport Line, and Build Your Own didn't show any of the M-Performance parts in the "options" or "accessories" pages.
