Expert Buying Guide for 2009 Porsche Boxster
For your 2009 Porsche Boxster, the 5x130 bolt pattern and 71.6mm center bore are critical. Aftermarket wheels must be hub-centric; use hub-centric rings to avoid vibration. The factory offset is 55mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always verify lug nut seat type: the Boxster uses ball-seat lug nuts (B 14x1.50). Using incorrect taper (cone) seats can lead to wheel loosening. Re-torque after 50-100 miles. Cross-compatible with 1997–2016 Boxster wheels.
