I have that BMW rim, it's a great quality rim.
I have the CSL Elite base though which at the time was about $500 cheaper than the V2.5. I also have an old V2 here which is marginally better than the CSL Elite but not $500 better, but looking at the prices between the CSL Elite vs the V2.5 with that BMW rim it's only a $200 difference now so I'd probably just get the bundle you're looking at.
What wheel do you have at the moment? And what pedals?
