A central lock for rims is usually not found on vehicles that drive on public roads. This is a device for a particularly quick wheel change from racing. And such fast wheel changes usually only take place during a pit stop at the race track. One finds central locking rims therefore almost exclusively on racing cars. But also some sports cars like that Lamborghini Aventador SVJ or the Porsche GT2 RSthat are approved for normal road traffic have such a device. To be more precise, this is not a closure as you might imagine it on bottles, rather the central closure for rims is a central nut or central screw. If this is loosened, the wheel can be removed from the vehicle or attached. And very quickly! This cannot be compared with a normal wheel change. Instead of the 4 or 5 small ones wheel bolts Only one big mother needs to be solved. And the central locks are usually tightened against the direction of the respective wheel. A left-hand thread is then on the right side of the vehicle.
little "everyday benefit"
For the use outside the pit lane but is, apart from a smoother running of the rim, no real advantage of a central locking system. Because in reality it looks like that with a roadworthy car you don't just stop at the side of the road and quickly change the wheel. And most vehicles nowadays no longer have a spare wheel anyway. Such a spare wheel would not fit in sports cars that have such a central lock for rims.
A complete rim with tires would therefore have to be carried along. But where to put it in a super sports car? In addition, it makes no sense to change the entire wheel. In the event of damage, it is sufficient to primarily change the tyre. Unless the rims are also damaged. From a visual point of view, however, such a rim with a central lock is an eye-catcher. Because the four or five screws on the rim, which are usually annoying from the optics, are not available. Although you can do it yourself "tune" the wheel boltsHowever, a central closure remains a central closure.
Disadvantages of the central attachment
There are only a few manufacturers who offer a central lock for rims. This means that the choice of rim suppliers is not large. In particular, the choice of 18-inch rims, as used on racing cars, is very limited. The biggest disadvantage is that you need a second person to change the wheel. This should be permanently on the vehicle brakes during the wheel change. If you didn't know, that's the driver's job in the pit lane when the mechanic is changing the wheel. At least if it is not a four-wheel drive vehicle!
And this is exactly what makes the central locking system on rims not really suitable for everyday use in a roadworthy car. The driver is often in a sports car, namely traveling alone. You also need special tools and even tuning workshops don't always have them to hand. And also one Central locking adapter has all of these disadvantages. In addition, there is the fact that the rim with the adapter moves significantly further outwards. A good alternative is that Central locking dummy, as we find. Only one thing should be avoided -> build the central locking optics yourself!
