ADR (Australian Design Rules) are the same standards your vehicle was built to at the factory. An ADR steering wheel upgrade is about keeping it that way.
Every vehicle sold in Australia goes through testing for steering, airbag safety and occupant protection. Swapping the factory wheel for an untested part means changing a safety critical component with no data on how it behaves in a crash.
A PVS ADR steering wheel is engineered as part of the steering and restraint system. That means design decisions and performance are documented and repeatable instead of guessed from appearance alone.
