Q: Why do I need a canceller kit to put coilovers on a 2026 Model Y Performance?

The 2026+ Model Y Performance uses a factory adaptive suspension that constantly talks to the car’s control modules. Remove the factory adaptive dampers for coilovers or air suspension and the car instantly detects the missing components, triggering suspension error messages, warning lights, and sometimes reduced functionality. This kit electronically simulates the factory adaptive dampers so the car operates normally on aftermarket suspension, which is why it is required for that upgrade.
