Fitting wheels on a Porsche 924

A Porsche 924 (1976–1987) uses a 4x108 PCD and a centre bore of 57.1 mm. Any wheel must match the vehicle's PCD exactly: there is no tolerance, unless you use a PCD adapter.

  • PCD: 4x108 required. See all vehicles with 4x108.
  • Centre bore: the wheel must have a centre bore of 57.1 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 57.1 mm.
  • Offset: the original is ET20. Compare your future wheel with the offset calculator (your vehicle is already selected) to see how many millimetres further in or out it will sit.
  • Fixings: thread M14x1.50, tightened to 130 Nm. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.

Frequently asked questions

What is the PCD of a Porsche 924?

A Porsche 924 (1976–1987) has a PCD of 4x108: 4 studs or bolts spaced around a circle 108 mm in diameter.

Does a Porsche 924 need a hub centric ring?

The centre bore (hub diameter) of a Porsche 924 is 57.1 mm. A wheel with a larger centre bore is fitted with a hub centric ring that brings it down to the hub diameter. A wheel with a smaller centre bore cannot be fitted.

What offset (ET) for a Porsche 924?

The recorded original offset is ET20. A lower ET pushes the wheel outwards, a higher ET pulls it inwards: check wheel well and caliper clearance before making any change.

What tightening torque for the wheels of a Porsche 924?

The specified tightening torque is 130 Nm for M14x1.50 fixings. Tighten in a criss-cross pattern with a torque wrench and check the tightness again after about fifty kilometres.

Which vehicles have the same PCD as a Porsche 924?

With the same PCD (4x108) and the same centre bore (57.1 mm), these include: Audi Convertible, Audi 80, Audi 100, Audi Coupe. Offset, width and rim diameter still need checking for each vehicle.
