The propeller steering wheel is a unique item, only the first fifty Spyker cars were made with this type from manufacture. After that Spyker stopped producing because of legislation reasons, they replaced the steering wheel fits to one from a Lotus, and later on to a airbagged steering wheel from a Lamborghini. The propeller steering wheel is simple to exchange with the old steering wheel because it's plug and play, all electronics are already in it! If you have an airbag steering wheel from the Lamborghini you also need a new indicator bracket. The time of replacing the steering wheel may take around 3 hours of work. With the Lotus steering wheel it will take around one hour. You can customise your steering wheel in the same leather of your car.
