991 GTS Center-Lock Fitment Tips
- This 991 GTS Center-Lock uses Porsche center-lock hubs rather than a conventional lug-bolt pattern. Confirm wheel compatibility, center-lock hardware, and torque/service requirements before ordering.

- Check brake clearance with the exact wheel design, not just diameter and offset.
- Use the wheel fitment calculator to compare poke, inset, and tire changes against your current setup.
