Expert Buying Guide for 1993 Porsche 928
For the 1993 Porsche 928, the bolt pattern is 5x130 with a center bore of 71.6mm. When selecting aftermarket wheels, hub-centric rings are mandatory to ensure proper load distribution and prevent vibration. The offset is critical: the factory range is around 50mm, but deviations of ±5mm may require fender rolling or suspension adjustments. Always verify lug nut compatibility: the thread pitch is 14x1.50, and the seat type must match—either conical (60-degree) or ball seat. Using incorrect lug nuts can lead to wheel loosening. For safety, re-torque after 50 miles of driving.
