Product Description

These wheel spacers are for 4 bolt wheels, 4x100mm pattern with an inside hub diameter of 57.1mm, as found on all 2002, E21 and E30 models (except the E30 M3). ONLY 12mm, 15mm and 20mm are hub-centric, it is physically impossible to have a hub-centric spacer for these cars less than 12mm thick given the chamfer on the face of the wheel hub. Material of the spacer differs by size, please see the list below. We sell our spacers in pairs, so if you order a quantity of 1, you will receive 2 spacers.

Available in the following thicknesses:

3.1mm – 1/8″ (Steel)

5mm – .20″ (Billet Aluminum)

6.35mm – 1/4″ (Aluminum)

8mm – .32″ (Billet Aluminum)

9.5mm – 3/8″ (Aluminum)

10mm- .39″ (Billet Aluminum)

12mm – .48″ (Billet Aluminum & Hub Centric)

15mm – .59″ (Billet Aluminum & Hub Centric)

20mm – .79″ (Billet Aluminum & Hub Centric)

Not sure what size you need? A simple “shade-tree” solution used to determine what size spacer is to grab a handful of 12mm washers. Stack the washers onto at least two of your wheel studs. At various intervals, test your wheel fitment. After determining your wheel’s optimal fitment, take the washers off and measure the thickness of the stack of washers. Then find a spacer in the closest available size.

Not sure if your nut has enough thread contact? A simple “shade-tree” rule-of-thumb is that the nut should be turned onto the stud enough to equal the thickness of the stud itself. With the 12×1.5 thread pitch, this equates out to roughly 8 full turns of the nut.
