986 Boxster Fitment Tips

  • Start with the 986 Boxster factory hub specs: 5x130 bolt pattern, 71.6mm center bore, and M14x1.5 hardware.
  • 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.
