If you're worried about heavy wheels, you won't want to get the VM CSL reps as the 19" are about 30lbs despite the manufacturer's claim that they weigh 26lbs. I had them and weighed them using my digital scale and also UPS' scale. Many members on M3forum.net weighed them and got the same results, around 30lbs. I've had 6~7 sets of aftermarket wheels on my Z4M & '04 Z4 3.0i, and can honestly say the VM CSL reps were the WORST wheels I've gotten because of how heavy they were. I ended up taking a big loss and got rid of them after less than 2 months. Acceleration was hurt slightly but trust me that's not the worst part. Handling & braking performances were greatly sacrificed. The car felt heavy and turn-in felt very unresponsive.

If performance is a concern for you, I'd recommend waiting for the forged CSL replicas which are said to be 20lbs IF (and that's a big IF) the manufacturer's claim turns out to be true.
