The car feels rubbery when it has a CDV. Removing it will make the clutch feel more direct, and easier to control. Drive with 3 fat guys in the car, or a trunk load of heavy heavy stuff, and you'll see what i mean.
I took mine to Car Tenders on Capitol Hill. They're a good independent shop and an authorized Dinan dealer (not that it matters). I purchased 2 valves from Seattle BMW and sent them to Zeckhausen to be modified. Zeckhausen kept one and sent me the other one. Car Tenders took about an hour to do the swap. Total cost was < $100. You won't spend a better $100 on your car. Enjoy your new ride.
