This is a superb upgrade to be able to paddleshift the gear changes and get a nicer steering wheel.
It comes complete with the steering wheel (which was retrimmed by Jack@Royal Steering Wheels (but only with blue stitching not tri-colour) just before I fitted it 6 months ago), round airbag (so can be fitted to facelift models), slipring (provide the connections for the paddles) and wiring harness (so no having to cut any wires).
If you collect I can even fit it all for you.
