Q: Why should I not run spacers with the CYBRHEX wheels?

Because the fitment is already engineered as a sporty OEM-plus setup, so spacers are unnecessary, and they can cause problems. UP notes that spacers with stud extenders may interfere with the wheel’s multi-drilled backpad, and the company cannot guarantee aftermarket spacer support. The width and offset are dialed in from the factory to sit right on the Model Y without rubbing. Adding spacers risks fitment and clearance issues the wheel was specifically designed to avoid.
