Rim width
Wheel rim width. This parameter determines the width of the tyre profile that can be used with this disc. When purchasing tyres, it is worth considering separately that the width of the disk should be less than the width of the tyre profile by 25 – 30%.
Offset
Departure is the distance from the plane passing through the place where the wheel is attached to the hub, to the plane passing through the middle of the landing width. Positive overhang values mean that the hub is on the outside of the middle of the disc,
negative values mean that the hub is recessed "deep" into the wheel. For each car model, there is an individual departure value that is optimal for stability and controllability.
Centre bore diameter
The diameter of the centre hole must match the diameter of the centering lug on the vehicle hub. It may also be larger; then adapter rings are used to install the wheel.
Hidden bolt pattern
The heads of the wheel bolts are covered with a special cover, the front surface of which repeats the overall design of the wheel rim.
The hidden bolt pattern allows the disc to look neater. Thanks to the cover, the bolt heads become less clogged, and it also protects the wheel fasteners from loosening/unscrewing. Additionally, the hidden bolt pattern makes the rims more harmonious and laconic.
