Dante, Thank you for your photos - you have a sharp eye !!
The 335i aero rear bumper is a definite improvement over the very conservative stock rear end. It reminds me of the E39/540i sport package rear end.
However, that 335i spoiler looks tacky.
I hope that there will be a lip spoiler offered, similar to the E46 coupe. As of today, BMW Canada has not received pricing from Germany on the aero package components.
