Downsides would be for anyone who is learning to drive manual on your car would likely stall it much easier. The CDV is there to close the clutch at a slower rate. It gives beginners smoother shifts and less chance of stalling the car.

With the CDV installed you can repeatedly stomp on your clutch in 1st gear quickly without applying gas and the car would not stutter or stall. With the CDV removed as soon as the clutch closes the engine would bog or die. In essence it slips the clutch.

A benefit of the CDV removal is if you're good at modulating your clutch, you should have a little less clutch wear.

Note to those with SMG's. The CDV is already removed as the computer determines clutch slip instead.
