ST Wheel Spacers

ST sorts its spacers into systems, and the system name tells you what comes in the box. D1 and D2 sets are plain spacers with a centring ring, used with longer wheel bolts or studs. A1 sets include the wheel bolts, A2 sets the wheel nuts, and D3 sets come with press-in studs. DZX and AZX sets include adapters, with AZX covering the thicker widths from 40 to 70 mm per axle. DZ and DZX+ sets add hub extenders, which lengthen the hub’s centring collar so the wheel still locates on it.

Widths are quoted per axle with the per-wheel figure beside them, from 6 to 90 mm per axle. Besides the bolt pattern and hub bore, every listing names the car’s original wheel fixing, such as an M12x1.5 nut or an M14x1.5 bolt with a 60° cone seat. That field is the quickest check that you are choosing the right system for your wheels.

The most common patterns are 5×114.3, 5×112 and 5×120, then 4×100 and 5×108. Longer fixings change the thread engagement, so torque the wheels to the vehicle manufacturer’s setting and recheck them after a short drive.
