Never connect the Quick Release Adapter (supplied
with the T818 base and sold separately) to the quick
release holder for screw base if you intend to use it on
a T818 base.
For use on a T818 base or a base equipped with a
connector for latch base, use only the quick release
holder for latch base supplied with Ferrari 488 GT3
Wheel Add-On.
