I guess rims from Frankfurt will make it to production, but it will be optional - not standard.

IMO facelift front and back suits the car better. The front has more agressive stance, the back looks more integrated to overall design, rear lights without circular graphics also suit better to Coupe design.

V8 is reserved for M3 premiere. I guess at this time the engine is not even ready for production, but still in testin phase.

So, V8 or even V10 engine could find place in CSL version of Z4 Coupe, if it makes it to production.
