Expert Buying Guide for 1994 Porsche 928
For your 1994 Porsche 928, the bolt pattern is 5x130 with a critical center bore of 71.6mm. Aftermarket wheels often have a larger bore, requiring hub-centric rings to prevent vibration and ensure proper load distribution. The offset is sensitive; the factory spec is 50mm, but a range of 45–55mm is acceptable. Deviating beyond this can cause rubbing or clearance issues. Always use lug nuts with the correct thread pitch (14x1.50) and seat type: factory wheels use ball seats, while aftermarket wheels may require conical seats. Mixing seat types can lead to loose wheels and catastrophic failure. Re-torque after 50–100 miles.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts to 95 lb-ft after 50 miles of driving.
- ✅ Ensure hub-centric rings are aluminum or plastic; avoid steel rings that can corrode.
- ✅ Check for clearance between the tire and suspension components when using wider wheels.
- ⚠️ Torque lugs in a star pattern to 100 ft-lbs (135 Nm), then re-check torque after 50-100 km (30-60 miles).

1994 Porsche 928 — Frequently Asked Questions
What is the bolt pattern for a 1994 Porsche 928?
The 1994 Porsche 928 uses a 5x130 bolt pattern (also called lug pattern or PCD). The center bore is 71.6mm and the offset is 50mm.
What other years of Porsche 928 have the same bolt pattern as the 1994?
The Porsche 928 uses the 5x130 pattern from 1993 through 1995. Wheels from any of these model years are dimensionally compatible with the 1994, provided the offset and center bore also match.
How do I measure the bolt pattern on my 1994 Porsche?
The 1994 928 uses a 5x130 pattern. For 4, 6, or 8-lug wheels, measure center-to-center across opposite holes. For 5-lug, measure from the center of one hole to the back of the opposite hole.
How tight should I torque the lug nuts on a 1994 Porsche 928?
Refer to your owner's manual for exact specs, but always tighten the N 14x1.50 hardware in a star or crisscross pattern. Re-torque after the first 50 miles of driving.
What is the PCD for a 1994 Porsche 928?
PCD stands for Pitch Circle Diameter, which is the same as the bolt pattern. For the 1994 928, the PCD is 5x130.
What does 50mm offset mean for the 1994 928?
An offset of 50mm means the wheel's mounting surface is 50mm away from its centerline. Changing this value drastically can affect suspension geometry and wheel bearing wear on your Porsche.
