Fitting wheels on a BMW 3 Serie E21

A BMW 3 Serie E21 (1975–1982) uses a 4x100 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: 4x100 required. See all vehicles with 4x100.
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 ET16. 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 M12x1.50, tightened to 120 Nm. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.

Vehicles with the same PCD and centre bore

Same 4x100 PCD and same 57.1 mm centre bore: wheels from these vehicles bolt on and centre on a BMW 3 Serie E21 without rings. Offset, width, diameter and caliper clearance still need checking.

What offset (ET) for a BMW 3 Serie E21?

The recorded original offset is ET16. 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 BMW 3 Serie E21?

The specified tightening torque is 120 Nm for M12x1.50 fixings. Tighten in a criss-cross pattern with a torque wrench and check the tightness again after about fifty kilometres.

With the same PCD (4x100) and the same centre bore (57.1 mm), these include: BMW Z1, BMW 3 Serie E30, BMW 2000C-CS-CA, Volkswagen XL1. Offset, width and rim diameter still need checking for each vehicle.
