997 GTS Center-Lock Fitment Tips

  • This 997 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.
  • Compare front and rear specs together, especially on staggered setups where tire diameter and offset balance matter.
  • 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.
